Khloe and Lamar might be joining the wad of celebrity couples getting a divorce.

With the ultimatum that Khloe has allegedly given the NBA star, the couple might be heading to splitsville. According to a report by Wet Paint, Khloe's sister Kim Kardashian is trying to get her to call it quits with Lamar.

"If anyone understands what Khloe's going through, it's Kim. She's been through rough patches with her boyfriend Kanye and her own divorce from Kris Humphries this year. She hates seeing Khloe like this," an unnamed source told Heat, as reported by Yahoo! OMG.

Kim has gone through an almost-same road with Khloe minus the cheating scandal, sex videos and drug problems with former husband Kris Humphries. She reportedly told Khloe that if she ever takes Lamar back, it should be the NBA star's last chance. If their relationship still won't work by then, Kim allegedly advised her sister to head for a divorce.

"Kim's advised her that if she's going to give Lamar another chance it needs to be the final one. Although she knows Khloe is hurting and is embarrassed that this is happening so publicly, she feels it might be better to call it a day like she did with Kris," the source noted.

TMZ says that Khloe, seemingly heeding Kim's advice, has issued an ultimatum - "get help or get an apartment," the report read.

Lamar has reportedly checked himself into a drug and alcohol rehabilitation center, says People. He was arrested for driving under the influence (DUI) last week after moving at 50 mph in a 65 mph freeway at San Fernando Valley. He was released after 5 hours with a bail of $15,000. He also had his license suspended for a year after refusing to take a chemical test at the jail.

Last summer, the NBA star was also enrolled in a 3-week treatment program in San Diego. A report says he stayed clean for the season while playing for the Clippers but was back to doing drugs when the season ended.
