David Arquette loves Courteney Cox with all "his heart" - but insists they aren't back together.

The actor and the former 'Friends' star announced last October they were going on a trial separation after 11 years of marriage, but speculation began to mount they may have reconciled after they were pictured together at Disney World, in Florida, last week with their six-year-old daughter Coco.

David, 39, insists he and 46-year-old Courteney are still estranged but are getting on well.

During an interview on Ryan Seacrest's KIIS-FM radio show, he said: "We're not together. She's my best friend, and I love her with all my heart. But we're not together, we're still separated."

But the 'Scream 4' star claims he and Courteney - who also appears in the horror sequel - are getting on great because they are "honest and open" with each other.

He explained: "We have 15 years together of love and Friendship. Our relationship right now is actually better than ever."

David also quashed claims his wife is dating her 'Cougar Town' co-star Josh Hopkins - who she recently went on vacation with to the Caribbean island of St. Bart's - and is adamant they are just friends.

The movie star - who checked into rehab to be treated for alcoholism in the wake of the split - said: "She went away to St. Bart's with Coco and her best friend and Josh from the show, and I know about all of this. But it's made out like there's some kind of scandal going on. But there's no scandal."
