Reese Witherspoon [1] had a big reason to celebrate at the Emmys on Sunday night: her show, Big Little Lies [2], won eight trophies! Luckily, she had her 18-year-old daughter, Ava Phillippe [3], by her side. The two met up after the ceremony at HBO's annual afterparty [4] and linked up with Reese's costar Laura Dern and her kids, son Ellery, 16, and daughter Jaya, 12. Aside from posing with her trophy, Reese opened up about her win [5], telling People it was "an out of body experience." "[It was] amazing, overwhelming," Reese said. "[I'm] so happy for my sisters in this process and this incredible family that we've built with HBO." Although a second season of Big Little Lies has yet to be officially confirmed, all signs are pointing to it being a go [6].
