Is a merger in the cards for two celebrity superstar families?
“Moses we might really become family when he marries Audrey!” Paltrow tells Hill, who interviewed her for January’s InStyle, on newsstands Friday. “My son is in love with your daughter!”
Paltrow is referring to her son Moses, 4, with husband and Coldplay frontman Chris Martin, and Hill’s daughter Audrey, 9, with country superstar Tim McGraw. The two families grew close while Paltrow and McGraw were filming their upcoming movie Country Strong in Nashville.
“Don’t you just love our babies?” Hill, 43, asks her friend, who replies, “I love mine, and I love yours!”
Hill complimented Paltrow on her singing voice, which Paltrow says “didn’t have any power or strength to it” before she spent time developing for her role as a country star.
“I don’t even know how to respond to that in your presence, but thank you,” Paltrow says. “You know, last night when I was watching the film, I thought, this is the best job I’ve ever done. Normally I can’t stand to see myself, but with this film I felt like it all came together.”
Paltrow, 38, also dished on her Christmas plans, saying the family of four will hole up in their Amagansett, N.Y., home for some R&R.
“I’m excited,” she says. “We always get a big old tree and go see movies. It’s so cozy.” Another bonus to the holiday season? “The phone stops ringing and the emails stop coming.”
