They grow up so fast!

Apple Martin--who turned eight on May 14--hit Jay-Z and Kanye West's "Watch the Throne" show at London's O2 Arena Saturday night (alongside mom Gwyneth Paltrow and brother Moses, 6) carrying a canvas tote bag and rocking a newly pink 'do.

Once inside the show, mom Paltrow, 39, tweeted a picture of her two kids paying homage to their "Uncle Jay" by throwing up the Roc-A-Fella records symbol.

Paltrow and her husband, Coldplay frontman Chris Martin, have spoken before about their close friendship with Jay-Z and Beyonce.

"Jay is one of the people I respect most in the world," the actress explained to Steve Stoute last November. "He's such an iconoclast in so many ways."

More recently, Paltrow opened up about her BFFs' first child together, daughter Blue Ivy.

"She's going to be an entertainer," Paltrow assured Hollywood Life after the Oscars in February. "She just has this glow around her like her mother."
