Patrick Stewart's wedding will be officiated by X-Men co-star and longtime friend Ian McKellen.

On British talk show "The Jonathan Ross Show," 73-year-old Ian McKellen announced that he would be performing the marriage ceremony at Patrick Stewart's wedding.

At the wedding, Patrick Stewart, 72, will be marrying fiancé Sunny Ozell, a 35-year-old jazz singer.

Stewart and Ozell have been together since 2009.

"I'm going to marry Patrick," McKellen said after he talked about his and Stewart's collaborations.

"No, no. How else do you put that? I'm going to officiate at his wedding," McKellen clarified.

When the host asked if McKellen was legally qualified to perform a marriage ceremony, McKellen replied, "I don't know. But in Massachusetts, in the middle of Amerca somewhere, you get anybody along, a friend, and I read out the words, and Sunny and Patrick will then be married. I declare you man and wife."

McKellen was referring to a Massachusetts law that offers a "one-day marriage designation". It allows people to obtain a temporary marriage license for $25 and a character reference.

McKellen has officiated a wedding before. He said on the show, "I've done it once before with two guys having a civil partnership. I was crying my eyes out."

McKellen is currently starring in a comedy series called 'Vicious' with Derek Jacobi. The series is about an elderly gay couple that has been living together for 28 years, according to the LA Times.

Stewart and McKellen will be starring together in X-Men: Days of Future Past, which also features Halle Berry and Hugh Jackman. It will be released to theaters on July 18, 2013.

Stewart and McKellen will appear on the Broadway revivals of No Man's Land and Waiting for Godot this coming fall.
