The couple was having dinner in a secluded area when John "took the guitar from someone who was performing and at the Chateau and performed an impromptu performance for Rashida." His audience included Paul Rudd and Jason Segel. The crowd "went wild when he performed his new song," an eyewitness tells Hollyscoop exclusively. Mayer got such a great response from fellow diners, he even performed his hit "Your Body is a Wonderland" for Rashida. Rashida and John left together in the wee hours...looks like Jennifer Aniston is out of picture!]
OMG! What kind of douchebag brings a guitar to a dinner date - and the offers up an "impromptu" performance? One that features a song you wrote about your ex-girlfriend ("Your Body Is A Wonderland" was penned for Jennifer Love Hewitt.) We're talking about John Mayer, so there's your answer! Rashida - what happened to rumors of a relationship with President Obama's whiz-kid speechwriter Jon Favreau? That's a much better match!
UPDATE: A lovely reader wrote in to alert me that Rashida's publicist has recently denied any romance rumors with John Mayer. As of today it is believed that she's still dating Jon Favreau. That's my girl! Thanks for the info Ella!

It's OK, they're not dating. Her rep has quickly denied it. She's most likely still with the speechwriter (or least I hope she is).
