Jake Gyllenhaal and Taylor Swift's Turkey Day PDATaylor Swift and Jake Gyllenhaal have been a hot topic of conversation for over a month after the pair were first spotted together at a 'Saturday Night Live' taping in October, but the duo have remained mum on whether or not they're more than just friends.

The latest cover of Us Weekly, however, indicates that the two are most definitely an item, showing the pair holding hands over Thanksgiving weekend in Brooklyn, where they spent time with Gyllenhaal's sister, Maggie.

The actor, who stars in the recently released 'Love and Other Drugs' with 'Brokeback Mountain' co-star Anne Hathaway, is smitten with Swift, according to sources. A friend of the pair tells Us, "It's definitely serious."

Swift, whose previous romances with celebs have been well-documented in both the media and on her albums, is reportedly just as thrilled about the new relationship. While it's rumored that the couple are taking things slow, sources say that they've already taken a serious step by meeting each others' families.
