Jessica Simpson Body Back

The newly svelte Jessica Simpson enjoyed a Saturday night dinner  with her sister Ashlee Simpson and hairstylist Ken Paves for dinner at Katsuya, in Hollywood.

“Jess is serious about getting her body back into fighting shape,” her pal reveals to OK!. “Working out is helping to give her focus and clear her head. It’s better than sitting around moping or throwing pity parties with ice cream sundaes.”
