Here’s a description of the character Melinda will be playing according to the casting call for the episode posted by SpoilerTV last December.

[DONNA] This attractive, refined and affluent woman in her late 30’s has sold an antiques-filled old house to Melinda. She has a deep sorrow in her recent past, an unsettled spirit that desperately requires Melinda’s assistance to move on…GUEST STAR.

When The O.C. vet Melinda Clarke joins The Vampire Diaries on March 25 as Matt’s MIA mama, Kelly, there will be a total of three MILFs in Mystic Falls who have formerly appeared as Jerry’s girlfriends on Seinfeld. Melinda played Alex, who preferred Jerry smooth-chested, on the NBC sitcom. Susan Walters, Tyler’s mom, Mrs. Lockwood, on VD, was Jerry’s infamous Dolores (aka Mulva). And Marguerite MacIntyre, who hunts vamps as Caroline’s mommy, Sheriff Forbes, played Jerry’s Miss America contestant date, Karen.

“I had no idea!,” says Diaries exec producer Kevin Williamson upon learning of the Seinfeld connection. “It wasn’t by design, but I wonder if there is some unconscious link. I was a Seinfeld freak.” So much so, he threw in a line at the start of the season that the sitcom was Stefan’s favorite. “It’s the greatest modern-day American comedy of all time.”

All three of Jerry’s exes pop up in Melinda’s first episode, titled “A Few Good Men,” in which Sheriff Forbes asks Damon (Ian Somerhalder) to participate in a bachelor auction officiated by Mrs. Lockwood. Beyond that, executive producer Julie Plec says that Matt’s mess of a mom will interfere in his relationship with Caroline, while Caroline’s mother will reveal to Damon why Alaric Saltzman really came to town. As for Tyler’s cougar mom, she’ll cope with her husband’s infidelity by trying to sink her claws into Damon.

Earlier that year she had also participated in the Reality TV Pilot “Giving, Celebrity Style” (a show that finds “ordinary extraordinary” people who deserve a Celebrity Make-Over to help their outsides match their insides) which was part of her involvement with ALS at the time. I have added two pictures of it into the gallery and a video sample can be seen below.

“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.”

Melinda’s first episode will air on March 25 when the show returns.

World Poker Tour and Commerce Casino will roll out the red carpet for the most glamorous stop on the poker circuit—the 8th Annual WPT Invitational. The exclusive, invitation-only event welcomes Hollywood celebrities, industry VIPs and world-class poker players who go head-to head in a freeroll Texas Hold ‘Em poker tournament for charity, $200,000 in cash prizes and eternal bragging rights. One hundred percent of the proceeds will benefit Chrysalis, a non-profit organization dedicated to helping homeless and economically disadvantaged individuals become self-sufficient through employment opportunities.

Be sure to keep checking back the site for full coverage of the event.

We assume that Melinda did not attend this event after all since there aren’t any pictures of her available.
