If you thought Amanda Bynes and Lindsay Lohan were friends, you were wrong. In actuality, the troubled actresses don't get along and want nothing to do with each other.

"She obsessively hates Lindsay," a Bynes pal tells Us Weekly. "She rambles about 'that bitch Lindsay' all the time."

It seems the dislike for each other started shortly after Lohan posted a tweet, claiming Bynes deserved the same punishments she got for reckless driving.

"Why did I get put in jail and a Nickelodeon star has had NO punishment(s) so far?" Lohan tweeted on September 16. And although that statement stirred the pot between these two former child stars, Lohan's rep insists "there is no feud" between the 26-year-olds.

Lohan has had a fair share of run-ins with the law over the past few years, but it's Bynes who's taking over the headlines due to her recent bizarre behavior and illegal driving habits.

The "Easy A" star is currently facing a DUI charge from an April arrest and two hit-and-run charges, as well as a charge for driving on a suspended license.

Says an insider close to her, "Amanda is spiraling out of control. She won't accept help from anybody . . . She's completely lost."
