You wouldn't have expected them to be an under-the-radar couple, but Benji Madden and Holly Madison are still together.

The pair started dating in December and things have only grown more intense from there.

In fact, reports In Touch Weekly, Madden and Madison will soon be roommates.

“Benji cares very much for Holly. They have been talking about living together,” a source said, adding that Holly will soon leave Las Vegas to reside in Los Angeles with Benji.

Last week, the two were spotted making out at an IT BOYS! music video shoot.

“Benji kept telling her how amazing she looked. They couldn’t keep their eyes off each other,” said a witness.
