Even though R-Patz and K-Stew rarely talk about their relationship, Kellan got honest in a new interview about their intense bond!

Robert Pattinson and Kristen Stewart may be one of the most famous couples in the world, but they usually keep very quiet about their love. But now their Breaking Dawn co-star Kellan Lutz is opening up about their romance!

Kellan, 26, was asked on Australian radio show Kyle & Jackie O how Rob, 25, and K-Stew, 21, were doing — and he wasn’t afraid to get real!

“I haven’t talked to them in a little bit,” he said. “It’s not really a question that I can answer because I don’t know them, but they seem adorable every time I see them and madly in love. You know — who knows. Hope the best for them, that’s for sure.”

Do YOU think Rob and Kristen will eventually come clean about their relationship, HollywoodLifers?
