Here's the thing about Awards weekends: by the time the actual event, in this case the Grammy Awards, rolls around on Sunday, you're already so exhausted from the consistent rush of red carpets, open bars and live exclusive performances that not everybody still has their "A" game left over (see Minaj, Nicki). Luckily, everyone still had enough left in the tank on Friday, when actors and pop stars alike came out for OK! Magazine's pre-party at TRU Hollywood, featuring live performances by Flo Rida and Pia Toscano.
