'Are You There Vodka? It's Me, Chelsea': Chelsea Handler Show Preview (VIDEO)

Chelsea Handler's got a starring role in the brand new NBC show based on her memoir. Weird, then, that she's playing her own worst enemy.

NBC, which announced last week the series pickup of the memoir-based "Are You There Vodka? It's Me Chelsea," unveiled a long teaser trailer for the show, which actually stars "That 70's Show" alum Laura Preppon in the thinner-than-paper "fictional" role of Chelsea Hanson. With the series based on her younger, wilder days, Handler herself plays Sloane, her (well, Preppon as her) older, pregnant, born again Christian sister.

The trailer contains plenty of canned laughter for what are largely easy jokes about DUI, alcoholism and STD's. So, for now, what seems to be a network-scrubbed version of Handler's talk show on E!, "Chelsea Lately." The show doesn't have a slot in the initial NBC lineup, but considering the shuffling the network has produced each season, it should hit airwaves sooner than later.
