This weekend the stars shared Instagram snaps that ranged from intimate at-home moments to travels to exotic locals. January Jones, who is gearing up for Mad Men's final episodes, shared a snap (above) of herself having a healthy snack ("Biggest raspberries I ever saw.") and Reese Witherspoon celebrated her 39th birthday with cake, candles, and a mariachi band. Also worth a look: Lady Gaga's full-glam and Jordin Sparks's no-makeup selfies—both gorgeous—as well as the most glamorous workout photo you'll ever see, courtesy of the newly engaged Bar Refaeli. See them and more of our favorite celebrity Instagrams from the weekend below.
