Stefanie Keenan/WireImage.comWatch out, Paris! There's a new heiress in town—and she knows how to throw a party.
Not only has Russian designer Kira Plastinina recently opened stores in New York and Los Angeles, she just turned 16 and had a star-studded soiree to celebrate.
On the pink carpet, Chris Brown gave me his advice for Hollywood newcomer Kira. "Just have fun, live it up and enjoy it!" he offered.
Although he chatted before his performance, his people made it clear that any questions regarding his romance with Rihanna were off-limits. But clearly, she was still on his mind...
He performed the version of "Umbrella" that they did together, asking the audience to sing her part of the song.
Another undercover couple at the party was Hayden Panettiere and Milo Ventimiglia. Although the twosome arrived together and held hands inside, they opted not to pose for any pics together. Photos or not, by the looks of their PDA, they're definitely on.
Also on the guest list for the posh party: Adrian Grenier, Audrina Patridge, Katy Perry and JoJo.
