Cheyenne Jackson Engaged! Glee Actor to Wed Entrepreneur Jason Landau

Couple has been dating since the summer

It's official—Cheyenne Jackson is getting married again.

"Cheyenne Jackson and entrepreneur Jason Landau are pleased to happily confirm that they are engaged," a rep for the Glee actor exclusively tells me.

Jackson's first marriage of about two years ended in divorce in September.

He and Landau were first reported to be dating in October. In December, they hit the red carpet together at the amFAR Inspiration Gala in L.A. (Jackson is an ambassador for the AIDS organization).

That same month, Landau was by Jackson's side at the TrevorLive benefit for the Trevor Project.

Jackson's career began on Broadway, where he's performed in Thoroughly Modern Millie, Aida and Xanadu. In film, he played Mark Bingham in the 9/11 drama United 93. He also appeared as one of Liberace's boyfriends in Behind the Candelabra.

He also played Danny Baker on 30 Rock and Dustin Goolsby on Glee, among many other projects.

Congrats, Cheyenne and Jason!

US Weekly first reported the new engagement.
