GUEST NO MORE: It seems that the suits behind ABC's hit medical drama "Grey's Anatomy" are making a habit of using guest-star spots as a sort of job interview for the show.

"The Hollywood Reporter" recently revealed that Kim Raver has been contracted to join the show full time, making her the third cast member to be promoted from a recurring guest to permanent star.

Raver was introduced to viewers for the first time as Dr. Teddy Altman back in a mid-November episode called "New History." Teddy was brought in to Seattle Grace by friend and fellow Iraq war veteran Dr. Owen Hunt (played by Kevin McKidd) as a much-needed cardiothoracic surgeon, but her history with Owen created tension between the two of them and Owen's girlfriend and co-worker, Dr. Cristina Yang (Sandra Oh).

Almost instantly, fans got a taste of the brewing love triangle when Teddy professed her feelings for Owen, but he turned down her advances and said he's in love with Cristina. Meanwhile, over the course of three episodes, Teddy slowly earned Cristina's respect as a surgeon when she took Cristina under her wing and assigned her the lead for an operation.

While the network has been tight-lipped about Teddy's future plot lines, it has been reported that, while Raver will appear in all but one of the season's remaining episodes, her new status with the series isn't connected to the rumors that Katherine Heigl may be leaving the show.

Interestingly, McKidd was one of the previous guest actors to be hired as a regular cast member. The other one was Jessica Capshaw, who plays Dr. Arizona Robbins.

Raver most recently starred in the short-lived NBC dramedy "Lipstick Jungle." She also has credits in "The Nine," "24" and "Third Watch."

SNOOP'S IN THE HOUSE: "One Life to Live" execs all seem to agree. They want another taste of Snoop D.O. Double-G.

ABC recently announced that hip-hop icon Snoop Dogg will return to the set of the long-running sudser for a second performance, which is set to air on Wednesday, Feb. 24.

The artist previously appeared in two May 2008 episodes, for which he remixed the show's theme song, performed at the Llanview club Capricorn and acted in a scene with Robert S. Woods's character, Bo Buchanan.

For his return engagement, Snoop Dogg's version of the theme song will once again be employed. He will share a scene with Woods again, as well as co-stars Hillary B. Smith and Eddie Alderson, who play Nora and Matthew Buchanan, respectively. Then, he'll return to Capricorn to perform "I Wanna Rock" from his December 2009 studio effort "Malice n Wonderland."

"As I said when I was here last time, I've been a fan of 'One Life to Live' since I was a baby because my momma always had it on," said Snoop Dogg. "It's cool to come back and hang with Bo Buchanan and the people of Llanview and rock out with them."

The series has become known in recent years for hosting a variety of musical performers, and executive producer Frank Valentini said they're glad to welcome the rapper back to the show.

"Snoop Dogg's desire to return to 'One Life to Live' is a tremendous show of support for our show," he said. "His unique contributions to the entertainment industry are vast as a performer, innovator and businessman and we are honored to have him back to perform and act on 'OLTL.' We also welcome the opportunity to once again air his remixed theme song."

The show has also previously welcomed artists such as All-American Rejects, Lionel Richie, The Pussycat Dolls, Mary J. Blige, Nelly Furtado and Lifehouse to its set.

ADAPTING A KING: Renowned author Stephen King is proving again that his work is well-suited for the screen.

Syfy recently announced that it is adapting King's novella "The Colorado Kid" into a new series, which it is calling "Haven."

Production on the supernatural drama is set to begin in the next couple of months, and the cable network hopes to debut the show before the end of the year. Produced by E1 Entertainment, the pilot episode was written by Sam Ernst and Jim Dunn, who previously worked together on "Shrek the Third" and "The Dead Zone."

They will also executive produce the series alongside Adam Fratto, Lloyd Segan and Shawn Piller, with Scott Shepherd (of "Tru Calling" and another King adaptation, "The Dead Zone") serving as the showrunner.

Syfy will be distributing the series globally, except in Canada and Scandinavia.

"Haven is the quintessential Stephen King town, full of complex, yet identifiable, characters and compelling supernatural situations," said Syfy's Mark Stern. "Sam and Jim wrote a great pilot, and we can't wait to see Scott, Lloyd and Shawn join them in bringing this town to life as a series. We also couldn't be more excited to partner with our international Syfy channels and be in business with E1, who will definitely deliver the high-quality production value we expect."

"Haven" takes place in its namesake small town in Maine, where people with special powers have gathered for generations because some mysterious energy seems to make them mortal, allowing them to live normal lives -- that is, until unexplained recent changes have prevented their powers from laying dormant.

Some of King's work that has also been previously adapted for the big and small screens includes "Rose Red," "The Shining," "Storm of the Century," "The Shawshank Redemption," "The Dead Zone," "The Green Mile," "Stand by Me" (based on King's novella "The Body") and "1408."
