Enjoying some vitamin sea 🌊

Because it's Friday ... and why not?!

Kate Upton led the charge with her sexiest of bikini selfies the other day, sunning herself on a boat someplace sunny and idyllic. The model captioned the shots, "Enjoying some vitamin sea 🌊," to which a fan replied, "wud u like some vitamin "D"😁???" Indeed.

The young Brielle Biermann, newly brunette, took the Instagram to poke some fun at herself and show off her sexy curves at the same time, captioning these shots, "Coconuts don’t fall far from the tree 🥥🌴" Clearly she has her mom's sense of humor!
