She just loves the old ultra-violence.

Fight fan Mandy Moore hosted Pure at Caesars Palace Saturday night while boyfriend DJ AM manned the turntables. Mandy Moore goes to so many fights she’s going to start hanging around playgrounds to egg on bullies.

Olympic gold medal sprinter Maurice Greene had a table at Pure nearby Phillies first baseman Ryan Howard. Jeremy Jackson and Mario Barth were also there, which was completely awkward when they came in dressed head to toe in Tampa Bay Rays gear.

Earlier, Moore and AM were at Social House inside Treasure Island where they were seated next to Jackson; while Criss Angel and Holly Madison also stopped in for a quick dinner before heading downstairs to Audigier. They didn’t stay long, bouncing over to LAX at Luxor. They settled in at their usual table before UFC fighter Joe Stevenson came in ahead of Greene, Jackson and Barth. Jackson and Barth mingled with the crowd instead of getting a table. Jackson must’ve learned from The Hoff that you’re better off being a man of the people.

The night before, Moore dined with three girlfriends at Lavo inside Palazzo before jumping on the club’s Escalade golf cart to zip up to Barney’s for late-night shopping. Nip/Tuck’s Kelly Carlson was at a separate table, while UFC fighter Kenny Florian settled in just after weighing in for Saturday’s fight. Rick Ross was also there, as was Geoff Jenkins of the Phillies.
