Do we have a Gossip Girl cat fight on our hands? Word on the street is that there’s beef between Taylor Momsen and Leighton Meester. According to HollywoodLife.com, Taylor is a little testy over Leighton’s recent rise to fame as a singer.

As you may recall, Taylor was the first cast member from the show to cross over to music, and she even has her own band called The Reckless, who toured with girl group The Veronicas this year.

But as of late, the only Gossip Girl being musically recognized is Leighton Meester. She collaborated with Cobra Starship on “Good Girls Go Bad” and just finished up a sexy duet with Robin Thicke called “Somebody to Love.” Taylor is anything but psyched for her on-screen frenemy, whose songs have been featured on episodes of the show. A source says, “Taylor is not happy that Gossip Girl has been playing Leighton’s music on the show, and they have never asked to play any of her songs. It’s creating a lot of tension on set.”

In addition to playing both of Leighton’s tracks on episodes, the CW also premiered the music video for “Somebody to Love.” And this is all before Leighton’s album has officially come out! Her solo record with Universal Republic is scheduled to come out early next year.

One source says there’s a reason for Leighton’s songs to be played over Taylor’s. “Leighton’s pop music fits the theme of Gossip Girl more than Taylor’s punk rock songs,” says the insider.

And a rep for the CW agrees, “The show will support Taylor and her music when the time is right, but her music is not ready yet.”

Ouch! That’s gotta hurt!
