You'd never know it was the middle of January by looking at Taylor Swift! The leggy singer showed off her sexy stems when she wore a tiny, oh-so-summery sundress after a trip to Ballet Bodies in Los Angeles on Wednesday.

Hitting the gym in midafternoon, the daring 25-year-old displayed her famous legs when she worked out that willowy body at the fitness studio. No parka, no sweater, no pants? We get that Los Angeles has amazing weather but it's not that warm! What is she thinking?!

We guess she was still hot from her workout! According to its website, Ballet Bodies, "draws from and improves upon the basic fundamentals of Pilates, with an ultimate focus on achieving an aesthetic as long, lean and beautiful as a ballet dancer’s."

Long and lean -- that certainly sounds like T-Swizzle! Sign us up!
