Ian McKellen is "going to marry" Patrick Stewart. The 73-year-old actor will officiate at the ceremony between his friend and X-Men co-star and his fiancee, jazz singer Sunny Ozell, when they tie the knot in Masachusetts.

"I'm going to marry Patrick [Stewart]. I am going to officiate at his wedding. In Massachusetts, in the middle of America somewhere, you get a friend along, and I read out the words, and Sunny and Patrick will then be married," he said in a television interview.

The British actor revealed it won't be the first time he has officiated at such a service: "I've done it once before with two guys having a civil partnership. I was crying my eyes out. I wore a white gown which I bought in India. You mustn't upstage the bride."

Massachusetts' Secretary of Commonwealth offers a service that allows a family friend or relative to perform a couple's wedding ceremony for a fee of $25. Patrick, 72, and Sunny, 35, have been dating since 2009.
