Amanda Bynes hates Lindsay Lohan

Actress Amanda Bynes reportedly hates Lindsay Lohan.

"She obsessively hates Lindsay," says the Bynes pal. "She rambles about 'that bitch Lindsay' all the time."

While a rep for Lohan insists "there is no feud" between the two actresses, both 26, are equally messy.

"Why did I get put in jail and a Nickelodeon star has had NO punishment(s) so far?" Lohan tweeted September 16.

Bynes, made a name for herself as a child star on Nickelodeon's sketch comedy show, All That.

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