Beyoncé and Gwyneth Paltrow in London

Beyoncé and BFF Gwyneth Paltrow pose with Roc Nation’s Ty Ty and Rita Ora backstage at Jay-Z’s show in London earlier this week.

Mr. and Mrs. Carter have a close relationship with Paltrow and her husband, Coldplay frontman Chris Martin. Their 3-year-old son Moses, who calls Jay-Z Uncle Jay, even listens to his music. “We put on the ’99 Problems’ video ’cause he’s obsessed, which is actually quite not appropriate,” she told Conan O’Brien in June. “He loves it and he sits there like this [arms crossed, nods head]. It’s the funniest thing.”
