After four divorces, Dame Joan Collins says she has found one way to keep a marriage happy – separate bathrooms.

The actress, 84,  wed Percy Gibson, 52,  in 2002.

She told The Mail On Sunday Life supplement: “We are together 24/7 except when he snores, and I say, ‘Darling, I think it’s best that you sleep in the guest room tonight’.”

Dame Joan added: “Michael Caine once said the secret to a happy marriage is separate bathrooms.

“I know most people don’t have that luxury, but in our homes, and whenever possible in hotels, we try to keep to that rule. It really does make a difference.”

She said: “Percy and I manage our lives together, even down to household chores.”

And she said: “We compliment each other all the time but I’m also quick to point out if he’s getting a bit of a tummy, and he will say if I’ve gone a bit OTT with the glitz.”

The Dynasty actress was previously married to film star Maxwell Reed, actor and singer- songwriter Anthony Newley, record producer Ron Kass and singer Peter Holm.
