Get ready for some serious shakeups in the Kardashian household! After a few days of feeling nauseous (and a couple of missed periods), Khloe convinces Kourtney to take a pregnancy test. But when the test comes back "sort of" positive, Kourtney knows she needs to break the news to her boyfriend, Scott. But are they ready to own up to the responsibility of being a parent? Or will this end up being just one big pregnancy scare? Also, Kourtney joins the rest of the Kardashian girls for a weekend in Sin City, but when Scott ends up popping the question after a night of drinking, will they end up at the altar in a shotgun wedding? You'll have to see it to believe it!

Picture Perfect: Kourtney's stress over a post-baby bikini photo shoot sparks a fight that pushes Khloe to leave Miami.

While opening up a new branch of their Dash boutique in Miami, Kardashian sisters Khloe and Kourtney try to keep their tempers in check, mentor their young employees, find romance and party until they drop. A spin-off of "Keeping Up with the Kardashians," this E! reality series finds Khloe hosting her own late-night radio show and Kourtney debating whether or not to reunite with her ex-boyfriend Scott.

In Season 2 of this reality series, siblings Kourtney and Khloé Kardashian go to Miami to rejuvenate their upscale clothing boutique, D-A-S-H. Between sisterly spats, Khloé hosts a radio show and Kourtney confronts boyfriend Scott about his drinking.

Kim and the rest of the Kardashian clan are back for another season of this hit reality show, which this year gets off to a dramatic start when sister Khloe and pro basketball star Lamar Odom breeze through a brief engagement and get married. But the fun doesn't stop there as the Kardashians -- whose stepfather is 1976 Olympic decathlon gold medalist Bruce Jenner -- find new and creative ways to stay in the limelight.

Despite their high-profile lives, the Kardashians try to keep things grounded in the third season of this cable reality series featuring siblings Kim, Kourtney, Khloe and Rob, mom Kris, her husband, Bruce Jenner, and their girls, Kendall and Kylie. From dating woes to sibling spats to touching family moments, cameras capture the Kardashian clan's ups and downs as they navigate life in the fast lane.

Romance is in the air in the series' second season as Kim poses for a sexy calendar for her boyfriend (gridiron superstar Reggie Bush), Rob falls for pop star Adrienne Bailon, and Kourtney and Kim set up Khloe on blind dates. Mom Kris shakes things up by getting a tattoo, while her husband, Bruce Jenner, is heading for a midlife crisis. Later, the girls travel to New Orleans and meet victims of Hurricane Katrina.

From producer Ryan Seacrest come this lively reality series that follows the ups and downs of the Kardashian clan, which includes mom Kris, her hubby, Bruce Jenner, and a mélange of six offspring. The first season blends spice and sentiment as daughter Kim poses for Playboy, the sisters fly to Mexico for a swimsuit shoot with Joe Francis (of "Girls Gone Wild" fame) and the family remembers Robert Kardashian on the anniversary of his death.
