Jessica Simpson and John Mayer were canoodling at New York's Hudson Hotel at a party thrown by Christina Aguilera on New Year's Eve. "He was scratching her back, they were kissing, it wasn't subtle," a source tells the New York Daily News. The "secret" couple then spent the night at the Mercer Hotel in SoHo. "John has been thrilled that they have been tricking the media, but she doesn't really care," the source says. John's Christmas present to Jess? A framed copy of the Us Weekly cover that says, "Dumped: John Ditches Jessica." That'll save her a little cash, which she'll need since she's not getting an expense check for her botched tribute to Dolly Parton. Jess won't be getting back the $15K she shelled out for hair, makeup and stylist fees for the fiasco.
