While we love seeing Blake Lively and Ryan Reynolds together, we especially love getting glimpses of Blake's close bond with her older sister, Robyn. On Monday, the two ladies attended L'Oréal Paris's Galentine's bash in NYC to promote the launch of their Paints + Colorista line. Robyn and Blake flashed big smiles for the cameras on the red carpet before heading inside and linking up with their mom, Elaine, to decorate cookies and mingle with beauty gurus. Blake shared a snap from the fun event on Instagram, writing, "Feb 13: Tonight's the night. Grab your best gal. 💋 I love my man. But on this valentines, I celebrate women. Time to party..." Hopefully this means we'll be seeing more of Blake and her family in the months to come!
