Kristen Wiig and Fabrizio Moretti PDA Pictures at Lexus Laws of Attraction Party

Lexus hosted their Laws of Attraction bash in San Francisco on Monday night for plenty of loved-up celebrity couples. The event's DJ, Fabrizio Moretti, brought along his girlfriend, Kristen Wiig. The couple, who usually are shy about press attention, didn't seem to mind kissing for the cameras. Jason Schwartzman also partied with his wife, Brady Cunningham. Brady and Jason enjoyed an adults-only night, leaving their 18-month-old daughter Marlowe at home. Jaime King, meanwhile, made the rounds with husband Kyle Newman. Model Devon Aoki also showed PDA with her partner, James Bailey.

Simon Doonan and his husband, Jonathan Adler, were the brains behind Lexus' new campaign, which was unveiled at the event. Photographer Ellen von Unwerth snapped photos of the famous pairs — kissing in front of Lexus cars — for a new range of advertisements. Simon and Jonathan, Kyle and Jaime, James and Devon, and Jason and Brady are all in the snaps — Kristen and Fabrizio are not.
