This week in the world of celebrity social media, we saw everything from on-set shenanigans to sweet family moments and a few stars making the most of the warm weather by hitting the beach — even in October! Miranda Kerr and Poppy Delevingne (she's the one in the Daft Punk helmet) were two such celebs that bared their bikini bodies, while model Bar Refaeli showed off her abs on the set of a photo shoot. Gwen Stefani and Rachel Zoe shared a cute moment as they put their growing baby bumps on display, and Ivanka Trump cuddled with her newborn son, Joseph, at his bris ceremony. Mindy Kaling and Whitney Cummings both hung out with adorable animals, while fellow funny lady Chelsea Handler dug into a rotisserie chicken. Speaking of dinner, Hilary Duff claimed that her son, Luca, made her cook the meal wearing a cat mask. Coerced or not, it's a cute look.
