Gwyneth Paltrow  partied with her mother, Blythe Danner, when she opened up her Goop pop-up store in LA on Tuesday night. The actress mingled with guests — including her mom and jewelry designer Jennifer Meyer , who is married to Tobey Maguire  — while dressed casually in boyfriend jeans and a blazer. The store is a big deal for Gwyneth, as it is her very first retail adventure and will focus on designs and products that she touts in her lifestyle newsletter, Goop. Gwyneth's estranged husband, Chris Martin , was not at the bash, but that doesn't mean that the "consciously uncoupled" duo aren't still friends, as the two were spotted grabbing dinner together  in Santa Monica, CA, just last week. Their meeting came after Chris gave an interview to BBC Radio 1  about his marriage, saying his "own issues" contributed to the pair's split.
