How better of a mom will Melinda Clarke be as Kelly Donovan than her “O.C.” alter ego Julie Cooper? Well it’s only a matter of time before we see Kelly’s maternal instincts with her hottie son Matt when she joins the “Vampire Diaries” (the show returns in March). And, Katerina Graham, who plays the bewitching Bonnie on The CW show, admits it’s nice to be reunited with TV’s number one bad girl.

“I was on the ’O.C.’ and I loved her on it,” Kat tells Hollywood Crush of Melinda’s stint as Zach Roerig’s sexpot mom on the show. “And I think she’s such a great actress and she’s so fun and a great addition to the cast.”

And while Kat and Melinda never got the chance to act in a scene together on the “O.C.,” Kat’s holding out hope that maybe the “Vampire Dairies” will give the ladies the chance to go head to head. “I never did a scene with her when i did the ‘O.C.’ and I don’t have scene with her as of yet, but just seeing her on set and stuff is pretty cool.”

Kat admits that the cast only wants to make sure that the show’s guest stars, like Sean Faris(may he RIP), feel comfortable working with the crew down in Georgia. “We’re a pretty close knit group and we always want to welcome any guest starts with lost of love,” she explained.

Are you excited for Melinda Clarke’s big arrival in Mystic Falls?

“I hope she stays a good witch. I think she’s such a great role model for a lot of girls,” Katerina Graham, who plays Bonnie Bennett on The Vampire Diaries, tells The Hollywood Exclusive.

Well Katerina may get her wish now that the CW has officially picked up The Vampire Diaries – its most watched show – for a second season. The show’s currently on a break until March 25, but when it returns, we’ll be on the look out for changes in the Bonnie storyline. Katerina, who was born in Switzerland and speaks English, Spanish, French and Portuguese, recently dished to TV Guide Magazine about her relationship with the rest of her TVD cast members.

“We’re very close,” she says. “We hang out all the time. We go to the movies, hang out at the mall, go to each others’ houses, go out to eat. We’ll still go to the Cheesecake Factory and order the same desserts we’ve always gotten.”

The Vampire Diaries is on an extended hiatus, leaving fans to wonder about how an influx of new blood suckers will affect Mystic Falls when the show returns on March 25.

Our prediction: not well.

In the meantime, the main Vampire Diaries cast members gathered this weekend as part of a nationwide mall tour and answered questions from fans in Los Angeles. TV Guide Magazine was on hand for the event.

Asked what’s in store for Elena and Stefan, Paul Wesley replied:

“There will always be conflict… Her mortality is a huge thing. What if she wants to turn? But for now they’re going to [be] a little less sort of serious and more like, ‘Let’s be a normal couple. Let’s laugh and do stuff that normal humans do.’”

But for how long can Stefan and Elena be happy when Damon is around? A bored, aimless Damon (due to the news about Katherine), no less?

“Damon having idle time, not having a mission, is a very, very problematic situation,” Ian Somerhalder said. “I think there are more shenanigans [to come].”

Echoed Nina Dobrev: “I think his presence always has an effect on their relationship, even if he doesn’t do anything… You’re definitely going to see a Damon, Elena, Stefan trio, the three musketeers.”

We’re also gonna see at least one more flashback to 1864 before the season concludes. Until then, remember to visit our Vampire Diaires forum and discuss the show with fellow fans.
