Charlie Sheen has reached out to Amanda Bynes.
The 'Anger Management' actor - who has battled drug addiction in the past - is worried about the troubled starlet and has sent word that he is available if she needs any advice.
A source told America's Star magazine: ''He's just offered to be there for her if she ever needs a friend. He's even offered her a guest spot on 'Anger Management' in case she decides to end her self imposed retirement from acting.''
Amanda isn't the only troubled star Charlie wants to help, as he has recently struck up a friendship with Lindsay Lohan, loaning her money to pay a tax bill and landing her a role in 'Anger Management'.
Speaking about his 'Scary Movie 5' co-star recently, Charlie said: ''I think she seems a lot more focused now than she was five, six months ago.
''There is a reason that I root for [her], because we fell in love with this little girl that was just an absolute genius and had this great light about her and that's still there.
''You can't extinguish that. I root for her because when you're that talented it just doesn't go away. Sometimes your appetites get in the way.''
