Tim McGraw's Simple Rules For Dating His Daughter

Gwyneth Paltrow recently revealed that son Moses, 4, has eyes only for Tim McGraw and Faith Hill's daughter Audrey, 9. So what does Tim think of Gwyneth's prediction that their two kids will get married in the very-distant future?

"That's what I hear. That's what I hear. Well, he better make a lot of money!" the singer laughs.

Tim says the kids aren't the only ones who get along well – wife Faith has developed a close bond with Gwyneth, his costar in the upcoming film Country Strong.

"They just enjoyed each other," Tim says of the families time together during filming. "The kids really had a great time, and we all had a lot in common."

Gwyneth, who is also mom to 6-year-old daughter Apple, and Faith would even head out for the occasional girl's night, while Tim stayed home with his three daughters – in addition to Audrey the couple also have Gracie, 13, and Maggie, 12.

"I babysat the whole time," he says. "Faith and Gwyneth went out and partied. I didn't get to go out...I was tired! So they went out. They had a good time."
