Chad Michael Murray, Tom Welling and Jensen Ackles

The CW has greenlit new seasons of Smallville (with Tom Welling on board), Supernatural, 90210, Gossip Girl and America's Next Top Model, the network announced on Tuesday afternoon

One Tree Hill also got picked up, though Chad Michael Murray's involvement in the seventh season is not yet a fait accompli, a source tells me.

Booking a half-dozen series in one fell swoop leaves little room on the CW's slate for new programming, especially since the pilots for a Melrose Place reboot and the Gossip Girl prequel, Lily, both are expected to be ordered to series.

Among the other pilots in play are The Vampire Diaries, a Twilighty drama based on a series of young adult novels.

Still straddling the bubble for the netlet are Reaper (launching Season 2 on March 3), Privileged (airing its freshman finale this Tuesday) and The Game.

Everybody Hates Chris is not expected to return, as it has produced enough episodes for syndication.
