The `Overboard` actress - who raised Kate with actor Kurt Russell - has hinted Kate and Matt, who have seven-month-old son Bingham together and have been engaged since April 2011, may have wed in secret.

Speaking in an interview with ES Magazine, Goldie said: "My kids are fantastic with their children, they have an amazing parental ethic and I`m very proud of them for that.

"When my daughter Kate married and English rock star [Matt Bellamy] it didn`t worry me; all that matters that the relationship is a good one. What people do is not necessarily who they are.

"Kate hasn`t picked up too many English mannerisms, she`s held on to her identity quite well."

Speaking last year, `Something Borrowed` beauty Kate said she and Matt - who began dating in 2010 - were in no rush to wed.

She said: "One thing at a time. We`ll say hello to our new one and enjoy that for a while."
