So, this being entertainment journalism and Paris Hilton having had a boyfriend for more than 40 minutes, she naturally had to field questions about getting married during her birthday celebration Saturday at Tao inside The Venetian. Because there’s nothing better than annoying wedding stories. Other than messy sex scandals and ugly divorce stories.

When asked the inevitable questions, Hilton said, “We’ll see what happens in the future but right now we are so happy to be together and we are really in love.”

So there you have it. Paris Hilton and Brandon Davis-fightin’ Doug Reinhardt are in luuuurve. Noted. Click for more words and pictures »

One more year in the 20s for Paris Hilton, who celebrates her 29th three days late at Tao inside The Venetian. So that should also mean Doug Reinhardt. And just a week after Spencer Pratt was in town. Hasn’t Las Vegas been through enough already? Click for more words and pictures »

It is, essentially, the most hoopla anyone has generated for starting a new Tumblr account, but Paris Hilton took over Vanity at the Hard Rock Hotel Saturday night to support the launch of ParisHilton.com, where she wasted no time dispatching her missives:

“Having the Best Time at Vanity at The Hard Rock Hotel :)” And don’t forget, “I Love Las Vegas. Xoxo Paris :)”

Excellent. Now that we’ve cleared that up, Hilton had dinner at Nobu on Friday with Doug Reinhardt and nine others before heading up to the club, where they stayed until about 3 a.m. Then on Saturday her crew ate at Rare 120 before hitting the club shortly after midnight. For the rest of Paris’ evening, check the pics on SpyOn.

Paris ‘n’ Doug — the rich man’s Spencer and Heidi — were at Body English Saturday night to celebrate Doug Reinhardt’s 24th birthday. Paris, naturally, had errands to run during the day. She had to stop by a pet store before they could do dinner at Rare 120, but then finally took over Body English along with Prison Break’s Amaury Nolasco and House’s Jennifer Morrison.

Hilton even rocked “Happy Birthday” on the mic, and we all know how those dulcet tones ring out. It was a special moment. They even found time Saturday to hit up Fright Dome at Circus Circus, riding the roller coaster and bumper cars. Good God, how much would you love to have Paris Hilton lined up in the sights of your bumper car? It would be worth however many tickets they wanted to charge.

Paris ex Benji Madden was over at Wasted Space, enhancing the night’s chance for awkwardness significantly. He was playing bass for Jason Ellis’ Tainstick during EllisMania, with Travis Pastrana and the rest of the Nitro Circus crew, along with Carey Hart and John Dolmayan of System of a Down.

First she went to town on headbands, now she’s doing sunglasses. Is there no accessory safe from Paris Hilton? Scrunchies? Brooches? Anklets? For the love of God, Paris, please spare the anklets!

Hilton did a fashion show Friday night at the Hard Rock Hotel pool where she showed off her shades from the Paris Hilton Sunglass Collection, from the House of Unimaginatively Named Eyewear. After she made sure everyone got an eyeful of her eyeful, she took boyfriend Doug Reinhardt to Nobu and then to Body English.

Earlier in the day, she was shopping inside Love Jones where she bought a pair of panties with Doug’s name on them. So, enjoy your nightmare fuel for the day everyone. We’re glad we could help. Oh well. At least they didn’t say “Spencer.”

Paris Hilton is into sunglasses now because … Paris Hilton, that’s why. Tonight, Hilton is poolside at the Hard Rock Hotel to debut her new collection from Gripping Eyewear. She’s on the runway to debut her signature shades of the Paris Hilton, which include the new style, Paris Party, featuring two live Chihuahuas swinging from each stem. Expect this to be a red-carpet hit in 2010. The fashion show runs from 8 to 10 p.m. Sweeping up all the Chihuahuas that broke off the sunglasses and fell to the ground should take until around 11.

Wow, Doug couldn’t look any more uncomfortable if he were getting tased. Which gives us an idea …

Simon Rex was enough of a draw to lure ex-girlfriend Paris Hilton to Prive inside Planet Hollywood Resort, toting along Doug Reinhardt Saturday night. This had all the makings of a gigantic trainwreck, but nothing exciting happened. Maybe they should’ve called Joe Francis. Rex, in his Dirt Nasty persona, was with Andre Legacy to do their thing when they were joined by Friday night’s performer, Mickey Avalon. Paris got on stage and on the mic for “Droppin’ Names” while she danced for a crowd that included Friday Night Lights star Scott Porter for his 30th birthday.

Avalon was at Strip House Friday night for dinner, as was Piers Morgan and Roger Clemens. And by “dinner” we mean “decadurabolin.”

Hilton also turned up at Wasted Space inside Hard Rock Hotel with Carey Hart for the Top 10 Maxim Hometown Hotties finalists.

Sweep the leg, Doug.

Doug Reinhardt was involved in another fistfight at a club over Paris Hilton last night. This is the second one in a month for those two. This one allegedly took place at h.wood in Los Angeles, according to RadarOnline.com.

A little after 1 a.m., while Paris and Doug were dancing a man came up to Paris and grabbed her chest … Doug immediately pushed the guy away, but the groper’s pal then threw a beer bottle at Doug’s head. (He missed.)”

After the last dust-up, Paris wrote, “FYI this is not in my nature to be in club brawls, I;ve never been around anything like that. It was totally unprovoked and thank God Doug was there to rescue me. A man should NEVER put his hands on a woman in that manner.”

While we’re baffled anyone would try to grope Paris, which we assume is like trying to grope a granite countertop, there are a couple of explanations here. One: people are so goddamn sick of Paris Hilton that they can’t contain their fury anymore, which would be kind of delightful. Or, two: these events are as set up as the Joaquin Phoenix heckler brouhaha. There’s also the off-chance that, three: Doug Reinhardt has been secretly trained by Cobra Kai for years.

If she started dating Ryan Reynolds, would anyone know the difference?

Britney weekend — which doubled as some kind of unofficial holiday, like a pre-Memorial Day that we’re shocked didn’t lead to government buildings being closed today — drew Paris Hilton, Nicky Hilton and Doug Reinhardt to town. They spent Saturday night with Jeff Beacher at Lavo inside Palazzo, where Stacy Keibler had a table full of blondes and Dash Mihok who was with a crew of 30.

The Hiltons moved over to XS at Encore around 3 a.m., along with Beacher and poker pro David Williams, though they made it a brief stay at 45 minutes. Also at XS, for the second night in a row, were Simon Cowell, Randy Jackson and Ryan Seacrest. Big Brother’s Beau Beasley was also there, in town for the Britney show.

On Friday, the Idol crew was in the owner’s section, while Jermaine Dupri also had a table at the club.

Paris Hilton did her last day of filming at the Hard Rock Hotel for Paris Hilton’s My New BFF yesterday. She brought out season 1 contestant Onch to hang with the BFFs-in-training while everyone filmed all day and into the night. Doug Reinhardt hung out behind the scenes. It’s tough to audition 20 girls to be your fake friend without a little moral support waiting in the wings.
