Ali Lohan heels tall robeks nipples No Bra

Despite recent reports that friends were concerned Ali Lohan “just keeps getting smaller and smaller,” the model seems to have a pretty healthy appetite!

Ali and a gal pal grabbed a bite to eat at Robeks in Los Angeles over the weekend, and the slim starlet showed off her long legs in a pair of high-waisted skinny jeans. But that wasn't the only thing 18-year-old Ali had on display ... it seems like she's taking fashion cues from her big sister Lindsay and stepping out without a bra!
