Kicking off the week with a visit to the late night circuit, Taylor Swift was one of the guests on-hand at “The Tonight Show with Jay Leno” on Monday (February 20).

The “Mean” singer prettied up the NBC Studios set in Burbank as she sat down with Leno to promote her upcoming movie “The Lorax,” which hits theaters on March 2nd.
Aside from plugging her new film, Miss Swift chatted about topics including what ‘mean’ really means and being stupid in love.

Of her tendency to be too trustful in others, the 22-year-old told, “I’m a Sagittarius and it says one of our major qualities is that we’re blindly optimistic. So when I’m in love I’m just stupid about it. And I trust people, constantly, and I’m always like, ‘I’m not gonna trust people anymore, I’m gonna be one of those dark, twisty girls who guys love because they’re all, like, guarded and stuff. And then I just trust people again… all the time!”
