Supermodel Adriana Lima admits she's struggling to lose the 40 pounds she piled on while pregnant with baby daughter Valentina last year.

She explained, "I'm going to be honest - it's not easy!" 

We can't really feel too sorry for  her. Adriana was recently named the second best-looking woman in America by Esquire magazine. She was beaten by "Mad Men" star Christina Hendricks.
