Cougar Town (8pm, ABC) - Two new back-to-back episodes of "Cougar Town" this week (I have the feeling ABC is burning them off and can't get the show over to TBS fast enough). In the first, hurricane damage to Grayson's place forces him to move in with Jules. In the second, the crew holds Thanksgiving in the spring (because they missed it in the fall) and there's an incident involving Big Carl.

It's directed by Joss Whedon ("Buffy the Vampire Slayer," "Dr. Horrible," "Firefly") and guest stars Neil Patrick Harris. NPH plays a jerk from Will's past and the two end up in a sing-off (Aerosmith's "Dream On"). Plus, there's a flashback scene featuring NPH with a mullet. Not to be missed.

I think I'm safe calling Scott Patterson's "Luke Danes" a heartthrob. Am I right, ladies?

Fans of "Gilmore Girls" who followed the Luke & Lorelai romance for seven seasons will be sure to tune in to "90210" in early 2010 when Patterson shows up as Liam's biological father. 

"90210's" showrunner Rebecca Sinclair is a former "Gilmore Girls" producer. And a saint. I've never ever watched "90210" but you better believe I'll be tuning in for this. 

The CW show, which airs on Tuesday nights at 8pm, also recently brought in Kelly Lynch to play Ivy's mother and love interest to teacher Ryan Matthews.

90210 (8pm, The CW) - Second season premiere has Annie still coping with the aftermath of her accident from last season. 

Melrose Place (9pm, The CW) - This much-anticipated remake of the legendary 90s soap is an homage to its predecessor, but it's also a bit more sophisticated. The writers will instill a sense of "anything can happen," so don't get too attached to any of the characters. There's a death in the first ten minutes of the premiere, and the rest of the season will revolve around solving the murder. Check back here on Wednesday for a recap.

Shaq vs. (9pm, ABC) - Tonight, Shaq puts on the gloves to fight Oscar De La Hoya. There will have to be some major restrictions on this fight to keep even an untrained Shaq from killing De La Hoya, since Shaq is more than a foot taller and twice the weight of the champion boxer.

Sons of Anarchy (10pm, FX) - Season two premieres tonight. Adam Arkin and Henry Rollins join the cast.

Flipping Out (10pm, Bravo) - Jeff hires a convict to replace weepy Rachel, who mercifully quit last week, saving Jeff the trouble of firing her behind. Why did he hire the ex-con? From viewing the previews I will venture that it was because he is pretty. It doesn't exactly work out.

If you've been waiting to catch up with Donna Martin since the original 'Beverly Hills, 90210,' tonight's the night she makes her grand return to the small screen.

Is she still married to David? What color is her hair? Why is she back in Beverly Hills? I can't wait to find out.

In case you didn't watch last week's episode (directed by Jason Priestley, a.k.a Brandon Walsh), you missed a real shocker.

Looks like bad girl Brenda Walsh is coming back to 90210 for the show's season finale.

Shannen Doherty, star of the original Beverly Hills 90210 and a guest star on The CW's new version, left the show earlier this season when her character got tangled up in some love triangle drama: Brenda hooked up with her friend Kelly's (Jennie Garth) boyfriend Ryan and then took off. 

Why is she back? "It is the finale, so you can probably expect a lot of drama," Doherty told E! Online.

Tuesday's "90210" has me wondering: Is Annie Wilson the anti-Donna Martin?

No matter how hard she tries, Annie can not get a guy to sleep with her.

Grandma Tabitha sends Annie off to her Palm Springs desert house for a relaxing getaway. Ethan tags along. She tells him she's ready to give it up. To him. Tonight. They start making out and stripping down. But wait. Ethan tells her that he can't go through with it because it's more than just sex with her. They are in love, after all.

Get ready for another "90210" reunion.

Donna Martin (Tori Spelling) and Brandon Walsh (Jason Priestley) will finally return to the zip code that made them famous.

According to People, Spelling "is close to finalizing a deal to be in multiple episodes," while Priestley is set to direct the March 18 episode.

I hope Kelly is excited to have her long, lost BFF back, since Brenda still isn't over Kelly stealing Dylan from her back in high school.
