This year's Met Gala brought out plenty of cute couples [1] and lots of fashionable friends [2], but there were also a handful of celebrity siblings [3] in the house. Mary-Kate and Ashley Olsen stuck together [4] on the red carpet (though, weirdly, didn't pose with their younger sister, Elizabeth) as did Jake and Maggie Gyllenhaal [5], who both showed off new beauty looks. Kim Kardashian met up [6] with her little sister Kendall Jenner, and though Beyoncé and Solange Knowles didn't hook up on the red carpet, they made sure to do lots of sisterly bonding at the afterparties [7]. Which siblings at this year's Met Gala looked the most glam together?
