Amanda Bynes has apologised for continually insulting Drake, insisting she now wants to be friends with the rapper.

There has been speculation about the 27-year-old star's mental wellbeing, after making a string of headlines over the past few months.

As well as being arrested for marijuana possession and briefly placed in a psychiatric hospital, Bynes has used Twitter to post rude comments about a number of stars including Drake, Rihanna and Miley Cyrus.

Drake is usually at the centre of her online rants, with the songstress labelling the rap star as "ugly".

She has now taken to the social networking site to call a truce - despite Drake never responding to the tweets.

She wrote: "I'm sorry about the tweets I said about @drake I didn't mean what I said. I hope to become friends with him instead of smashing him! (sic)."

Cyrus recently told a US radio station she didn't want to feud with Bynes after she also called the singer "ugly".

She explained: "I won't even entertain that thought. I think it's all so sad and I don't want to add any fuel to that fire. It's so sad to me. I was rooting for her comeback until she started attacking me, and I just thought it was hilarious that she mentioned my name the moment I was the worldwide trending topic on Twitter."

Bynes responded to Cyrus' comments, writing: "Thank you for rooting for me doll! You are one of the prettiest girls! I want my nose to look like yours after my surgeries! (sic)."
