After helping John Mayer ring in his birthday on Wednesday, Jennifer Aniston spent the afternoon of his 31st visiting Cahuenga Elementary School in LA. The photos of the celebration at House of Cigars in Beverly Hills aren't great, but you can see her big smiles the following day. The smartwater was present as always as were her perfect hair and that Cabo tan, must be nice. While John didn't come to add his musical touch to whatever she was up to at the school, I wonder if she had more special birthday fun up her sleeve for her on again guy.
