Fresh on the heels of Khloe and Rashad's Jan. 28 split, Life & Style can now exclusively report that both Robert Kardashian and Kourtney Kardashian have also split from their respective loved ones! Does the same fate await Kim and Reggie?

A family insider filled in Life & Style on all the romantic turmoil:

Rob, 22, and girlfriend Adrienne Bailon, 25, split because "it just got too hard," says the insider. "They are just so young. She is very career-oriented, and he's still in school." Luckily for this couple, it wasn't a bitter breakup. "They are still friends, but it's definitely over."

For Kourtney, 29, and her fiancé, Scott Disick, his cheating ways ultimately led to Kourtney calling off their engagement. "Kourtney and Scott have been having problems for a while, and Kourtney finally got tired of Scott's fidelity issues," the insider reveals. "He was openly flirting with other women -- and probably more. He was also partying harder and harder. Kourtney called off the engagement, and they split a few months ago."

And as Life & Style already reported, there is no hope for Khloe, 24, and her ex-boyfriend, the Minnesota Timberwolves' Rashad McCants, 24. "Rashad is still trying to use Khloe for publicity!" the insider says. "He flew himself to Las Vegas last weekend and tried to crash a party that Khloe was hosting, but Khloe thinks he's a loser."

Kim, 28, and her boyfriend, NFL star Reggie Bush, 23, don't intend to let the same fate befall them. "When Reggie heard about all the Kardashian breakups, he called the sisters and told them to keep the breakup energy away from Kim. He says that he's determined to avoid this 'Kardashian curse,'" the insider explains.
