"I've had a marvelous day, and now my gorgeous Sue is the new Mrs. Goodman," he told the Daily Mail.

Goodman, 68, and Barrett, 47, have been together for more than 10 years.

The couple reportedly wed in a surprise ceremony. The 30 friends and family he invited thought they were attending a Sunday lunch, according to the Daily Mail.

"I wanted it to be a low-key affair, so we didn't tell anyone except my 96-year-old mum as I didn't want her having a heart attack with the surprise," he explained.
