Chelsea Handler will play her own older sister in the pilot based on her novel 'Are You There Vodka? It's Me, Chelsea.'

According to E! Online, Handler will star opposite Laura Prepon in the NBC pilot. Prepon will play a fictionalized version of the E! host.

"I haven't read [her books]," Prepon told E! "But I've seen her a lot and it's going to be awesome. I am just starting to immerse myself in the Chelsea Handler of it all. She's an amazing woman.

"I'm from Jersey," Prepon said. "Chelsea and I are similar, so it's perfect we play sisters. It's funny, because her vodka is my favorite vodka too. We both drink the same thing!"

Comedian Jo Koy has also joined the pilot cast. According to the Hollywood Reporter, Koy will play a bartender at the club where Prepon works.

True Blood is on hiatus until next year, so I'll do whatever it takes to feed my fixation -- even if it means bringing down a popular pastor and televangelist. I came across this picture of Joel and Victoria Osteen (above, left) -- he's an author, TV host, and pastor at Lakewood Church. I'm sure they're doing wonderful things in the world and helping lots of people.

But really, just look at them. They're Steve and Sarah Newlin from True Blood (above, right). There's no mistaking it, and I have to wonder if Alan Ball had the Osteens in mind when he wrote the parts for the Newlins, played by Michael McMillian and Anna Camp.

Somehow, I feel certain that Joel and Victoria Osteen aren't harboring a grudge against vampires (though I'm sure they work against evil in the world) or holding poor souls captive in their church basement, like the Newlins did at the Light of Day Institute.

Still, it's hard not to see the similarities, isn't it? Both couples are based in Texas, too.

I'm always ravenous for any True Blood news, and this week, EW.com's Michael Ausiello posted about two new cast members joining the HBO vampire show.

Anna Camp has signed to play the series-regular role of Sarah, wife of Rev. Steve Newlin (Michael McMillian), the head-honcho preacher from the Fellowship of the Sun Church. The church is an anti-vampire religious sect, and I'm sure the addition of Sarah will shake things up good, since she hates vampires with a passion. Her character is described as in her late 20s, pretty, feminine, and part of the new hip evangelical movement. Camp is no stranger to controversial projects, as she's currently starring opposite Daniel Radcliffe in the Broadway production of Equus.

Ashley Jones (Dr. Bridget Forrester on The Bold and the Beautiful), has been tapped for a six-episode arc as Daphne, a new waitress at Merlotte's. Rumor has it that she won't be hanging up her stethoscope on the soap, but will juggle both shows. Hmmm, I'm seeing a blood theme in her roles.
