Actor Cheyenne Jackson, who is best known for guest spots on Glee and 30 Rock, is divorcing his husband of two years, physicist Monte Lapka.

“Cheyenne Jackson and his husband Monte Lapka have mutually decided to divorce,” a statement from Jackson's representatives reads. “The couple have been together for 13 years and were married in NY State two years ago. It is an amicable parting and, understandably, a private matter.”

The 38-year-old Jackson plays Dustin Goolsby, the musical coach of rival team Vocal Adrenaline, on the Fox musical-comedy Glee. He also played Danny Baker on the NBC sitcom 30 Rock, which ended earlier this year after 7 seasons.

Jackson has also played many prominent roles on Broadway, where he was last seen in The Performers.
