Then I went to New York and she came too, then she came here [to London] and surprised me, so that's pretty baller," Jaden said of Kylie. "She's one of my best friends. It's pretty awesome." Indeed, when Us broke the news of the new couple, a source said the young stars had "been friends forever."

"I went to his hotel. I gave him his Cartier. And then I went to see Kanye West perform," he says. "I got him the Love Bangle, not the watch. It cut him, but yeah, he thought it was cool." .
