It's the news Chuck and Lost fans have been waiting for -- at long last, NBC and ABC have chosen premiere dates for their two fan favorite drama series... drum roll please...

• Lost: Tuesday, February 2

Both series kick off their new seasons with a special two-hour premiere episodes. Chuck's Sunday premiere will be followed by its regularly scheduled episode on Monday night at 8pm ET (check local listings). Heroes will then move back to their former 9pm ET timeslot.

The February 2 premiere of Lost begins at 8pm ET with their obligatory recap special, followed by the two-hour premiere. The series settles in to their new Tuesday night home the following week at 9pm and is expected to stay put until the very end. [Get the scoop on the final season]

The Twilight Saga... True Blood... The Vampire Diaries... Let's face it, we're addicted. For those who have yet to get in on the CW's newest hit series The Vampire Diaries, the network is giving viewers a chance to take on a whole new obsession this December.

Beginning December 14 through December 18, the CW will air all 10 episodes (two episodes a night) of the vampire series in consecutive order. It'll be the most delicious week of the holiday season and very low in calories.

Will you choose Team Stefan or Team Damon? After watching the first 10 episodes, choosing sides may be as difficult as that whole Edward/Jacob ordeal (I have yet to pick a side). One thing is for sure -- it's one of the hottest and most intense triangles on television right now!

In light of this vampire craze, I wonder if CBS is regretting canceling Moonlight so prematurely?

The bitch is back and ready to make life miserable for anyone who dares to cross her -- Heather Locklear returns as Amanda Woodward on Melrose Place this week!

When we last saw Amanda, she and Dr. Peter Burns (played by real life boyfriend Jack Wagner) conspired with Michael Mancini to fake their deaths and the two appeared to live happily ever after in some beautiful tropical locale.... or so we thought.

Apparently paradise wasn't enough to keep Amanda happy. While I don't have details on what happened to Peter, I do know that she has a shiny new boyfriend and is running WPK Public Relations. Her very first scene is with Ella and Caleb, where she starts things off with a bang with the following statement:

"This L.A. branch is drowning in red like a steer in a slaughter house. Now when I hired you to give this place a makeover, I didn't mean smear it with lipstick and turn it into a five-dollar hooker. This office is pathetic."

Will Locklear's return be enough to save this ratings-challenged series from the almighty axe? I think it's safe to say that if there isn't a significant improvement in the next few episodes, Melrose Place won't be long for this world.

No network is complete without the requisite medical drama series, and the CW is finally joining the ranks by adding one of their own to the primetime schedule.

According to The Hollywood Reporter, the CW is forging ahead with HMS, an ensemble drama about a group of students at Harvard Medical School. And here's where it gets interesting -- Heroes star Hayden Panettiere is going to serve as co-executive producer.

Amy Holden Jones, who penned hit movies such as Mystic Pizza, Indecent Proposal and Beethoven, will write and produce the series, which was first shopped to the now-defunct WB five years ago.
