Kate Upton's curvaceous figure has earned her two highly-coveted Sports Illustrated covers.
But the supermodel has revealed that she doesn't always appreciate her famous assets.
"I wish I had smaller boobs every day of my life," she told The Sun.
"I love to wear spaghetti tops braless or go for the smallest bikini designs… Every single day, I'm like, 'Oh man, it would be so much easier,' especially if people didn't constantly bring them up.
"If only I could just take them off like they were clip-ons."
She added that she was, however, proud of her shape. "I love my boobs and I'm proud of my size.
"That's an important message to young girls – love who you are. It's so easy to feel negative about yourself and it is totally self-destructive.
"If you can only love and accept who you are you will be a lot happier."
Kate is making her acting debut with her first major role in comedy The Other Woman, alongside Cameron Diaz.
"In my eyes, Cameron Diaz has the perfect figure," she continued. Speaking about the character she will be playing, Amber, she said, "I think it's funny to act like a dumb blonde. I know that's not the case so why not play on it?"
Kate's body hang-up admission comes just days after fellow supermodel Kate Moss revealed she was insecure about her "bow legs".
Talking to The Sunday Times about her new Topshop collection, the model was asked if she had any rules for dressing herself.
"No rules apart from heels, and I never do mid-calf," she said. "I've got bow legs and I can't."
