Robert Buckley has slowly but surely been moving up the Hollywood ranks, kicking off his career with a role in MyNetworkTV's nightly drama 'Fashion House' alongside the likes of Bo Derek and Morgan Fairchild. But his big break came playing Kim Raver's boy toy Kirby on last year's drama 'Lipstick Jungle.'

Now Buckley is joining 'One Tree Hill' as the show enters its seventh season and loses mainstays Chad Michael Murray and Hilarie Burton. With the Sept. 14 premiere on the horizon, Buckley spoke to AOL TV about the direction the show will take, why he's not comfortable being "the hot guy" and his take on Hollywood cougars. -- By Katy Kroll

'One Tree Hill' newlyweds Lucas and Peyton are taking a permanent honeymoon.

In other news, Fox has renewed 'Lie to Me,' Alanis Morissette is fired up to do some "tasteful nudity" on 'Weeds,' and Starz is going to keep 'Party' going.
