Kim Kardashian "needs alone time"

Kim Kardashian is not just sitting around after breaking up with Reggie Bush. According to her sister, Kourtney, the reality star has been looking to make a life change.

"We actually went looking for houses yesterday," Kourtney Kardashian told Ryan Seacrest on his KIIS-FM radio show Wednesday morning. "She found some to-die-[for] houses."

The Keeping Up with the Kardashians star says her sister is doing relatively well as a newly single woman. "[She] just needs alone time and [to] focus on herself," Kardashian says.

Still, Kourtney says the Kardashian clan feels no ill-will against Bush. Says Kourtney: "My mom just said she's going to [football] training camp and lugging him back."
