While it's all fun and games for One Tree Hill's Nathan and Haley when the Season 7 premiere starts next Monday night, at the end of the hour "something (or maybe someone) puts their happiness into serious jeopardy," according to sources.

Any thoughts on who or what that could be?

Fortunately, shirtless Robert Buckley and others will help lighten up the mood in the first episode. At least "four sets of pecs and abs" will reportedly be on display.

Wow. One Tree Hill quotes plus Robert Buckley shirtless equals the greatest premiere in the history of TV. Or at least the CW on Monday at 8 p.m. EST. Woohoo!

Robert Buckley shirtless. Does it get any better than this?
