Meanwhile, Kylie's mother Kris Jenner, 58, recently admitted that she has a "very close" relationship with Jaden, whose parents are Will Smith and Jada Pinkett-Smith, and sees him as one of her own kids.
She said previously: "He is the greatest kid in the world.
However, the March 1 event was allegedly soured when Cirque du Soir turned Bieber away for bringing along underage friends including Smith and 17-year-old Ella-Paige Clark.
It's not a confirmation, it's just an idiot's assumption about things." Kylie, 16, was reportedly spotting locking lips with Jaden, 15, at her half-sister Kim Kardashian's wedding reception in Florence, Italy, on May 25, after he'd accompanied her to the romantic nuptials.
However, the 'Keeping Up With the Kardashians' star got tongues wagging on Friday () when she was photographed cuddling up to her friend Miles Richie, 20, in her car before the hunk leaned in for a smooch.
The 58-year-old Kardashian family matriarch told the Huff Post Live: "He is the greatest kid in the world.
I'm very close to Jaden and he's like one of my own, you know." The 'After Earth' star and Kylie, who previously insisted they were just good friends, were spotted "making out" at her half-sister Kim Kardashian and Kanye West's wedding in Florence, Italy last month. He looked so good, and so fun, and he also has a really good sense of humour." Kris revealed that Jaden wore the costume all night and she even borrowed his shoes the next day, as her feet were sore from her high heels.
getting to that age when the ladies are definitely interested... "Probably the best advice he's ever given me is, 'Don't have a girlfriend,'" Jaden revealed.
