Amanda Bynes has conceded that she underwent a nose job and has pleaded with magazines to stop using pictures of her old look. "The reason I've asked all magazines and blogs to stop using old photos of me is I don't look like that anymore! I had a nose job to remove skin that was like a webbing in between my eyes," she said in an extended Twitter post on Sunday.

The teen television star - now 27-years-old - has been in the headlines again recently following a handful of bizarre tweets. She recently told fans she had to drop 35 pounds. "I wasn't going to tell anyone, but I look so much prettier in my new photos that I don't want old photos used anymore!," she tweeted over the weekend. "When will they stop? I will never look like that again!" Bynes, who has certainly changed her image in recent years, assured fans that the surgery was "the most amazing thing for my confidence," and received a flurry of supporting tweets for fans. One said, "You're so pretty though! You are the queen!!!"

Bynes - who is now more famous for her erratic behaviour than anything else - shot to fame as a child star on 'All That' before landing her own sketch show 'The Amanda Show.'
