Here are a TON of celebrities attending a wedding reception at the Oviatt Hotel in LA. Even though WENN didn't say who the bride and groom were, there is SO much to talk about from this set!Look who is still going strong. In matching black, Jessica Biel and Justin Timberlake walked out of the party hand in hand equally looking dissatisfied with the paparazzi's coverage. Tobey Maguire and his wife attended although not photographed together. Tobey is obviously a very good tipper because he dropped $20 to the valet for getting his car. And Miss Eva Mendes looked like she really enjoyed herself showing off her beautiful smile and hopping into her car with that looker.Click on the thumbnails to enlargeWENN
