blake lively william baldwin gossip girl 320 CW Sweeps Scoop: 'Vampire Diaries,' 'Smallville,' 'Gossip Girl,' 'One Tree Hill' and '90210'May Sweeps is upon us, and The CW is bringing its A-Game. As the 2009-2010 season draws to a close, your favorite shows have more twists and turns than ever.

Zap2it has the scoop on what’s to come for “Gossip Girl,” “90210,” “The Vampire Diaries,” “One Tree Hill,” and “Smallville.” Consider this your spoiler alert:

When “Gossip Girl” returns, so will Serena’s dad. Billy Baldwin stars as William Van Der Woodsen, and he’s not going to make things easy for Rufus when they bump into each other at Lily’s aparment. In the season finale, Georgina (Michelle Trachtenberg) is back. Of course, she’s never just in town for a visit — she’s got a definite agenda. Blair and Chuck’s future together will hang in the balance, all leading up to a possible showdown on top of the Empire State Building. We’ve confirmed with The CW that when the series returns in the fall, Jenny (Taylor Momsen) will be M.I.A. … no news yet on how she’ll make her great escape from the Upper East Side.

All is not well on “One Tree Hill.” Skills returns from California to find out that Mouth, his best friend, has been hanging out with Miss Lauren. Meanwhile, Haley is still coming to terms with her mother’s death, and her grief will spiral into depression. Nathan, Jamie, and the rest of their friends will convince her to join them in Utah for Julian’s movie premiere. The season finale — which was actually shot in Utah — may be the last we see of the Tree Hill gang, as The CW hasn’t yet renewed it for Season 8.

On “Smallville,” Tess will break into Watchtower – and Chloe’s elaborate security system will backfire, trapping both of them inside. Clark is going to realize that Zod has juiced his soldiers wtih super powers. He and Chloe will search for the Book of Rao to find out how to stop the army, but Clark will be a little bit preoccupied by a visit from his mom (Annette O’Toole) and her new boyfriend. When Clark and Zod have their final showdown to gain control of the planet, Chloe will call for backup… bringing back a few familiar faces.

mia kirshner ian somerhalder vampire diaries 320 CW Sweeps Scoop: 'Vampire Diaries,' 'Smallville,' 'Gossip Girl,' 'One Tree Hill' and '90210'Will Stefan’s new human blood habit drive Elena into Damon’s arms? “The Vampire Diaries” will never be the same after Stefan and Damon finally tell Elena how they became vampires in another highly-anticipated flashback episode. Damon and Alaric will continue their reluctant partnership as they try to get the jump on Jonathan Gilbert, who is headed for a messy fight with Pearl. A mysterious invention — possibly dreamt up by the original Jonathan Gilbert in 1864 — will bring Isobel back to Mystic Falls, but Elena’s first meeting with her birth mother won’t end well. Not everyone will survive the season finale on May 13.

So much for no-drama-Adrianna on “90210.” She’s going to record a duet with a sexy pop star (played by Diego Boneta), and their subsequent romance will put a wrench in Navid’s plans to confess his feelings for her. Teddy’s dad (Ryan O’Neal) isn’t fond of Silver, but despite his dad’s insistence that they break up, Teddy and Silver plan to take their relationship to the next level.

What are you most looking forward to? We can’t wait for Georgina on the UES, and Stefan’s more interesting than ever now that he’s given in to his vampire urges.
