Taylor Swift hits ex-boyfriends in live track

Taylor Swift performed a song about her "douche-bag" ex-boyfriends on Saturday (07.11.09).

The 'Love Story' singer hosted US TV show 'Saturday Night Live' where she performed a quirky song about getting revenge on her former beaus and her love for her current boyfriend, actor Taylor Lautner.

She sang: "I like writing songs about douche-bags who cheat on me / But I'm not going to say that in my monologue / I like writing their names into songs so they're ashamed to go out in public / But I'm not going to say that in my monologue."

The blonde beauty – who split from Disney singer-and-actor Joe Jonas, 20, last November - used her appearance on the popular weekend show to brag to her ex-boyfriend about her growing success.

She sang: "You might think I'd bring up Joe Jonas, that guy who broke up with me on the phone / But I'm not gonna mention him in my monologue.

"Hey Joe, I'm doing real well. Tonight, I'm hosting SNL. / But I'm not gonna brag about that in my monologue. La la la. Ha ha ha."

The 19-year-old songstress has been dating 'Twilight' actor Taylor Lautner over the past few months.

Although they have not been together long, Taylor used the opportunity to declare her love for the 17-year-old hunk.

She mouthed, 'Hi Taylor', before blowing a kiss and winking at the camera and singing: "And if you're wondering if I might be dating the werewolf from 'Twilight' / I'm not gonna comment on that in my monologue."

The teenage singing sensation also used the evening to speak about Kanye West's behaviour at the MTV Video Music Awards (VMAs) in August.

Singer Kanye stormed the stage, interrupted her acceptance speech for Best Female Video and told the audience he thought Beyonce Knowles should have been given the honour instead.

Taylor quipped: "You might be expecting me to say something bad about Kanye and how he ran up on the stage and ruined my VMA monologue / But there's nothing more to say / 'cause everything's okay / I've got security lining the stage."
