'Radiant' mom-to-be Kristin Cavallari hits Fashion Week

Mama-to-be Kristin Cavallari made the rounds at Fashion Week Monday. The reality gal started her day at Rachel Roy's morning presentation, wearing a forgiving draped matte jersey dress by the designer. Since her next show - Betsey Johnson - wasn't until 6 p.m., she met fiance Jay Cutler for a lunch of soup and salad at Marble Lane.

"She was very smiley and looked radiant," a witness told amNewYork.

Later that afternoon, Cavallari headed back to Fashion Week headquarters at Lincoln Center, where she popped by the Mercedes-Benz Star Lounge for some recharging (but she skipped out on the sushi, which she said she's missed eating during her pregnancy) before taking her seat at Betsey Johnson.

On Tuesday, she saw the Dennis Basso show.
