Patrick Stump knew he needed a makeover after he posed for a special snap with U.S. President Barack Obama - and failed to recognise himself in the photo.
The singer met Obama in 2009 on the night the politician was inducted into the White House and was stunned by a picture they took together because he was practically "hidden" from view by his accessories.
Stump decided then to lose weight and swapped his trademark hats and shaggy sideburns for slim-fitting suits and a cropped haircut.
He tells WENN, "I met Obama the night he got inaugurated. I looked at the photo and you can't see me in it because I'm behind all this stuff.
"That's something I'm going to show my grandkids and you can't see it because I was so caught up in these accessories.
"It became this thing of, 'What hat is he going to wear today? I love your sideburns, can I touch your sideburns?' People were really attached to these things. I got really scared. (Entering Fall Out Boy), I didn't know that this was the only outfit I was ever going to wear.
"When I had the opportunity, I was just like, I'm going to stop this and dress how I wanna dress!
"I had the hat, I had the sideburns, sometimes I had glasses - a lot of things to hide behind. My face wasn't really out there."
