Swift—who just landed eight Grammy nods—recently wrote on her MySpace blog that the holidays are her "favorite time of year. Hands down."

"I love everything about this time of year, but mostly the way that people find ways to be with the ones they love," wrote Swift, who is dating "New Moon" hottie Taylor Lautner. "And I love sweaters. Everyone is wearing sweaters right now."
