Rihanna, the lost fourth member of TLC.
Rihanna spent her afternoon yesterday lounging around Marquee Dayclub. And then she spent the rest of her night shooting the shit out of stuff at the Guns and Ammo Garage during a private midnight session, which we assume is just her taking some sensible and necessary precautions in case Chris Brown shows up uninvited to her house one night.
And because I Heart Radio is in town this weekend, Ryan Seacrest and Justin Timberlake both spent time at Tryst last night. Seacrest was with two friends near the waterfall, while Timberlake, in a separate group, was there with a 20-dude bachelor party. They, of course, were drinking his 901 Tequila. Because someone has to.
