Ashlee Simpson and Pete Wentz put aside their impending divorce yesterday and reunited for lunch with their son Bronx at the Beverly Hills Hotel in LA. It was a special Valentine's Day meal for the trio, one of their first public outings as a family since Ashlee filed for a legal separation last week. Despite their gathering, Ashlee is reportedly living with her parents Tina and Joe in Encino, CA. The problems in their nearly three-year-long marriage come as Ashlee's sister Jessica is prepping for her own wedding with her lunch buddy Eric Johnson. Jessica recently recounted the story of Eric's proposal for New York magazine, and cryptically tweeted last night, "9 1/2 Weeks! Happy Valentines Day!" It's unclear, though, if she's referring to the movie, pregnancy, or something else entirely — what do you think?
