A Gossip Girl source confirms that Broadway vet Aaron Tveit is reprising his role as Nate’s wealthy cousin, Tripp Vanderbilt, in November for at least six episodes.

The politically minded Tripp will announce that he’s running for office (possibly the senate) and Nate will get involved with his campaign. Holley Fain, who portrayed Tripp’s fiancée, will also be returning for multiple episodes.

Tripp was mentioned in the season premiere by Nate's grandfather, who, in a bit of foreshadowing, called him about a way to potentially stick it to the Buckleys.

Tveit will juggle his Gossip Girl arc with his Broadway gig in Next to Normal.

In other Gossip Girl casting news, actress Sarah Steele (Spanglish) has been cast in a potentially recurring role of Kira Abernathy, a Constance Billard girl who tries to befriend queen bee Jenny. Her first episode airs November 9.
