Just weeks after dumping Taylor Swift, Jake Gyllenhaal seemed too cruel for words as he spent hours cozying up to her nemesis — gorgeous actress Camilla Belle — at the Grey Goose-sponsored Art of Elysium Heaven Gala in LA. “Jake was sitting next to Camilla, and he was very chatty and flirty with her,” says a fellow partygoer at the January 15 event. Jake, who just a day later brought his ex-girlfriend, singer Jenny Lewis, to the Golden Globe Awards, has left Taylor more humiliated than ever. “Beneath it all, Taylor is a hurt little girl,” a friend tells In Touch of the country cutie, who was devastated two years earlier when her boyfriend, Joe Jonas, left her — reportedly for none other than Camilla. For her part, the sultry 10,000 BC starlet, who hammed it up in a revealing Jason Wu outfit at the From Prada to Nada premiere in LA on January 18, was coy when asked about her new companion. “He’s obviously a really talented guy,” she told In Touch of Jake.
