Kaia Gerber stepped out for dinner with her close pal Tommy Dorfman in a stunning, ab-bearing outfit. The supermodel, 18, showed off her toned midriff when she reunited with the 13 Reasons Why star for a meal in Los Angeles on July 31. Kaia rocked a black crop top and high waisted denim jeans, which she paired with black booties. Of course, she also donned a protective face mask, and allowed her honey highlighted hair to fall just above her shoulders.
