Could Paris Hilton beat her BFF Nicole Richie down the aisle?
Asked on Yo on E! if he could be engaged within six months, Benji Madden replied, "I'm not gonna bet against you on that. We'll see. I'm very, very happy right now."
The rocker, 29, added that "nothing would make me happier" than spending the rest of his life with the heiress, 27.
Madden said he's always known the "real Paris.
"I always knew that she was, like, wife material, or serious girlfriend material," Madden said.
Any one who finds true love in their life "is really lucky," Madden added. "You know you just walk around feeling lucky all day. You just want to get on top of a mountain and go, 'I'm in love!'"
Also in love? His twin bro, Joel.
Benji said "it wouldn't surprise" him if Joel married Nicole Richie, the mother of four-month-old daughter, Harlow.
"They're madly in love, I can tell you that," he said. "They're like the picture-perfect couple, and they're amazing parents."
When would they tie the knot? Said Benji, "Your guess is as good as mine."
