Len Goodman has no problem voicing his opinions on Dancing With the Stars, but kept his engagement and wedding to longtime girlfriend Sue Barnett as quiet as possible.

The long-standing judge told Access Hollywood Live revealed that not even his wedding guests knew they were going to be attending a wedding! He invited 30 close friends to a restaurant for what they thought was going to be a casual lunch, but shocked them all after bringing everyone up to the second floor for a surprise wedding.

"It started at 2, finished at 5... Lovely lunch, all my friends... If I get married again, which I never will, I would do it like that," he said. 

However, Goodman admitted that he felt obligated to tell his mother about the ceremony beforehand due to her age.

"She's 96. I thought I had to tell her or she'll faint or something," said Goodman.

It's the second marriage for the 68-year-old dance judge and the first for his 47-year-old wife. His last marriage came exactly 40 years ago, but he said he has remained on friendly terms with his ex-wife.

"You end up getting married, but of course when you stop dancing... once that's done, there's very little in common," said Goodman of his first marriage. "The connection was dancing and we're still friends. She married a multimillionaire lives in Monaco and she's got a lovely apartment... And a maid's apartment, but no maid. They invite me down to stay there!"

Goodman has been a judge on Dancing With the Stars since 2004 and has been the head judge on BBC show Strictly Come Dancing since 2011.
