Gigi Hadid and Kendall Jenner grabbed lunch at Canter's Deli in Hollywood on Saturday afternoon, and while Gigi kept it casual in an athletic-inspired outfit (at first glance we thought she was in her gym clothes -- oops!), Kendall got all glammed up for the occasion.

Last month the ladies joined pal Lewis Hamilton on a yacht in Monaco, but after partying their butts off in bikinis, they've been laying low at home. Gigi has been spending time with her mom Yolanda Foster, who has been battling Lyme disease for quite some time now.

Gigi recently opened up to E! News about her mom's struggle and said, "You know it's hard, especially with something like Lyme disease, not a lot of people know about it, especially doctors so they don't really know how to help, medical wise. So it's really hard for me and my siblings to know how we could help, but I guess just being supportive is the best way we can do it." We're glad she's there for her mom -- and we're glad friends like Kendall are there for her!
