Celebrity designer Rachel Zoe stepped out with her two sons – Skyler, 4, and Kaius, 2 – in Beverly Hills, Calif. on Saturday (March 5).

Joined by the nanny, the designer-reality star, 44, and her boys walked hand-in-hand while shopping for children’s clothes at The Grove.

Later that day, the proud mama shared a shot of her sons via Instagram.

‘Happiness on a Saturday afternoon #brotherlylove #itsthesimplethings #bestfriendsforever XoRZ,” she captioned the image of her boys enjoying a sweet treat.

Last month, we spotted Rachel and her family-of-four – including husband Rodger Berman – in Brentwood.
