Courtney Love has urged Amanda Bynes to "ignore the haters".
The troubled actress was arrested on Thursday night for possession of marijuana, attempted evidence tampering and reckless endangerment.
She allegedly threw a bong out of the window of her New York City apartment onto the street below.
Bynes has vehemently denied smoking cannabis, claiming she is allergic to it and only smokes tobacco.
After a series of bizarre tweets posted by Bynes after her detainment, Love requested on Monday via Twitter that the former TV star "pull it together dude".
