Would You LOOK AT THAT . . . Ashlee Simpson Appears To Have GROWN A BUTT . . . Is That From Her Pregnancy . . . Or Is It FAKE?? (PICS)

: Ashlee Simpson was photo’d out in Los Angeles yesterday, and we couldn’t HELP but to notice that she was a heck of a lot CURVIER than she used to be.

We know that she had a BABY not too long ago, so maybe her body’s just changed.

Then again, she does live in Los Angeles – home of PLASTIC SURGERY – so anything is possible.

Ashlee got two babies: son Bronx with daddy Pete Wentz, and her daughter Jagger Snow with new hubby Evan Ross (Diana Ross’ son).
