Amanda Bynes looks like a much different girl these days -- and part of it is due to plastic surgery!

Over the weekend, the former child star revealed she went under the knife a few years back while explaining why she hates seeing magazines and websites using old photos of her all the time.

"The reason I've asked all magazines and blogs to stop using old photos of me is I don't look like that anymore," the 27-year-old tweeted on Sunday.

"I had a nose job to remove skin that was like a webbing in between my eyes," she explains. "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 seems pleased with the results.

"I will never look like that again," Bynes adds. "Having surgery was the most amazing thing for my confidence!"
