Ever since Jenny (Taylor Momsen) took over as Queen Bee of Constance Billard, there’s been a lot of on-screen tension between her and former monarch Blair (Leighton Meester). Now rumors are swirling that the tension extends off-screen… for an entirely different reason.

Reports Hollywoodlife.com:

Sources tell HollywoodLife.com exclusively, “Taylor is not happy that Gossip Girlhas been playing Leighton’s music on the show, and they have neverasked to play any of her songs.  It’s creating a lot of tension on set.”

Gossip Girl used Leighton’s songs “Good Girls Go Bad” and”Somebody To Love” during two episodes this season, and the CW showeven premiered her music video for “Somebody To Love.”  They have neverused any of Taylor’s songs.

The gossip site cites their mysterious source again as saying that the reason behind the apparent “favoritism” is that “Leighton’s pop music fits thetheme of Gossip Girl more than Taylor’s punk rock songs.”

They also apparently spoke with a rep for the CW, who said, “The show will supportTaylor and her music when the time is right, but her music is not readyyet.”

Do you believe the rumors that Momsen is mad at Meester’s music, and would her anger be justified?
