Literally, out of nowhere, rumors erupted that Lindsay Lohan and Chaka Khan had beef due to Lohan’s behavior at a rehab center that they both attended.

Radar Online claimed:

“Chaka was really cool about everything at Cliffside, but Lindsay just pushed all of her buttons to the point where she was aggravated and tired of Lindsay’s sh*t,” the former patient told Radar in an exclusive interview.

“Lindsay was just doing stupid stuff for attention, so Chaka told her she was childish and told her to grow up. She never lost it, but started yelling at Lindsay. Told her to knock it off, asking her if she came to rehab to get well, or just to piss around.”

Things got so heated between the two that the source tells Radar 60-year-old Chaka eventually had it with Lindsay, telling several of the patients she “hated” Lindsay. “Chaka was so annoyed with Lindsay. It got so bad that she refused to get in the same car with her or go to the same meetings with Lindsay,: the source said.

“So Cliffside had to change everything up schedule wise so the two were never together.” Chaka — who has admittedly struggled with drug abuse and alcoholism in the past, spending several stints in rehab centers — left Cliffside a week early because she couldn’t stand Lindsay, the source claims.

“Chaka told me she was leaving early because she couldn’t stand Lindsay,” the source told Radar.

“Lindsay caused such an uproar that administration basically said to the patients, ‘If you can’t take it and you want to leave, leave.’ The next day a guy that had already left because of Lindsay came back and helped Chaka with her bags and stuff and took her from Cliffside.”

However, if we’re going by their tweets, all is good ’round their way:

I love this. Hopefully, Chaka shows up on Lindsay’s OWN reality show.
