They’re two of the biggest stars in fashion, double-billing on the covers of Sports Illustrated, Vogue and Vanity Fair and lusted over by countless admirers — still, Kate Upton can’t stand them reports The New York Post.

“I wish I had smaller boobs every day of my life as I love to wear spaghetti tops braless or go for the smallest bikini designs,” the supermodel and actress tells Britain’s The Sun on Sunday.

“Every single day, I’m like, ‘Oh, man, it would be so much easier,’ especially if people didn’t constantly bring them up,” she confesses of her two biggest assets.

At least twice a day she wishes she were smaller up top, Upton, 21, admits. “But the grass is always greener, as they say!”

If only they were a little more like . . . earrings, the covergirl muses of her natural-born 34-D’s.

“If I could just take them off like they were clip-ons.”

Upton is co-starring in “The Other Woman” with Cameron Diaz and Leslie Mann. All three women bond when they plot to take revenge on the man who cheated on them all. In it she plays a ditzy blonde.

“I think it’s funny to act like a dumb blonde. I know that’s not the case so why not play on it?” she tells The Sun.

“But I actually don’t look at my character as dumb,” Upton continues. “I think of her as young and naive, like I was once.”
