The return of Donna Martin helped 90210 show signs of ratings life last night.

A week after falling under the two-million-viewer mark, the series earned 2.1 million for its latest episode. It was the remake's largest audience in two months.

Among other primetime pickings:

• American Idol (23.5 million viewers) was up from a week ago.

• Dancing With the Stars (14.8 million) was also up. A rerun of The Mentalist likely helped.

• Fringe (11.5 million) is looking like an official hit.

With the ninth season finale of CSI bearing down on fans, many are wondering what sort of cliffhanger the drama will deliver.

To find out, TV Guide talked to actor Wallace Langham, who plays David Hodges on the series. He said the self-contained episode will feature Laurence Fishburne's Raymond Langston in danger:

"You see him put into some situations that are new for him, as far as being out in the field and having to deal with perpetrators."

What about Hodges? He gets to stay in the lab, as usual.

There's no doubt that music is a big part of the new 90210.

With that in mind, we've added a feature that allow fans to browse the songs from each episode, listen to samples and purchase them on iTunes, and even look up the lyrics.

Here's a sampling of some of the new songs we added today from "Off the Rails," "Life's a Drag," and last night's "Okaeri, Donna:"

• Gavin Rossdale - "Love Remains The Same"
• Lily Allen - "Not Fair"

• Franz Ferdinand - "Ulysses"
• Lenka - "We Will Not Grow Old"
• The Kills - "Cheap And Cheerful"
• Attack! Attack! - "You and Me"

You can browse the rest by going to our 90210 music section. Enjoy!

Thatcher Grey is coming back to Seattle Grace.

The third season of Mad Men will premiere in early August.

We'll pass along the exact date when AMC announces it.

Betty Draper ended season two with a baby on the way. Where will this story pick up in season three?

As for what fans can expect from season three, words of advice: don't expect tidy resolutions to the second season finale's cliff-hangers - i.e. Peggy's admission to Pete and Betty's pregnancy - because the show is likely to jump ahead in time again.

Hmmm... what 1960s historical events might serve as a metaphorical backdrop (as the Cuban Missile Crisis did in Season 2)? Perhaps a certain Presidential assassination.

Do you remember when Miles blackmailed, - err, tried to extort - Ben for $3.2 million dollars during Lost's fourth season? 

Okay, we know it was awhile ago, but Miles offered to pretend like Ben was dead in exchange for a cool $3.2 million.

Why the arbitrary amount And why would the blackmail at all? 

According to TV Guide, we're gonna find out why, as a dollar amount other than the $3.2 million is brought up in tonight's Miles-centric episode, "Some Like it Hoth."

Got any guesses before the hour airs, readers?

Supernatural may be on a several week-hiatus until it returns with its controversial episode, "Jump the Shark," but our Supernatural spoilers never get a vacation.

Previously, the show's producers have hinted that Steven Williams would reprise her role as Rufus this season. Looks like the producers are sort of holding up their end of the bargain.

According to TV Guide, Sam and Dean will hear Rufus in the May 7th episode, "When the Levee Breaks."  Guess we'll have to settle for just his voice for his season four appearance. 

For the upcoming April 27th episode of The Big Bang Theory, "The Vegas Renormalization," in which Leonard and Raj take Wolowitz to Las Vegas to get over a breakup, we previously hinted there would be hookers involved.

Now we have the name and actress behind one of the prostitutes.  The beautiful Prison Break alum Jodi Lyn O'Keefe will guest star as Mikayl according to TV Guide.

As for Sheldon, well, as we already told you, he'll be stuck having a sleepover with Penny after locking himself out of his apartment and his potential "weekend of dreams."

Quentin Tarantino as a mentor?

Only two judges critiquing performances at a time?

As if Donna Martin's return to the zip code that made her famous wasn't enough, last night's 90210 also featured a naked male model; sex in the woods; and enough Dr. Pepper shilling to last a lifetime.
