Supermodel Bar Refaeli says she prepared for her Sports Illustrated swimsuit cover by stuffing her face.

Leonardo DiCaprio’s girlfriend is steaming up newsstands posing on the front of SI in a skimpy bikini.

And the Israeli says she was told by magazine bosses to keep herself curvy before the magazine came out.

“They tell you to eat cheeseburgers, ice cream, whatever – just don’t lose weight,” Refaeli said.

“Me, I didn’t even work out. I ate whatever I wanted. It was the best.”
