The American Horror Story star cited “irreconcilable differences” as the reason for their split.

American actor Colton Haynes has filed for divorce from celebrity florist Jeff Leatham.

TMZ confirmed the news after obtaining Colton’s divorce documents, which cited “irreconcilable differences” as the reason for their split.

Rumours around their split began last week when the couple unfollowed each other on social media and removed photos of them together from Instagram.

Colton took to Twitter to dismiss any rumours of Jeff being unfaithful: “Jeff would never cheat. He is an amazing man. Please stop being mean to him. The song I wrote was about a past relationship.”

The Teen Wolf star and Jeff married last October in a star-studded ceremony in Palm Spring, California.

The ceremony was officiated by Kardashian matriarch Kris Jenner, and guests included AHS: Cult co-star Cheyenne Jackson, Chelsea Clinton, Sofia Vergara and her husband Joe Manganiello, Jesse Tyler Ferguson, and Billie Lourd.

Their split comes just months after Colton’s mother Dana tragically passed away from organ failure.
