Beverly Hills socialite Nikki Haskell was as shocked as anyone when she learned NFL players have been taking her Star Caps weight-loss supplement.

New Orleans Saints offensive guard Jamar Nesbit sued Haskell last week, claiming Star Caps were improperly spiked with bumetanide, which is banned by the NFL. Nesbitt, who served a four-game suspension, wants Haskell to pay him $235,294 in lost salary. He also wants damages for his reputation.
