As previously reported, Justin Bieber partied with Kim Kardashian and her irritating family over the weekend, helping friends celebrate the 40th birthday of designer Riccardo Tisci.
But the real news isn't with whom Bieber partied... it's with whom Bieber left the party:
According to The Sun, Bieber made a “beeline” for Kendall as soon as he arrived and the young stars were “inseparable” most of the night.
An onlooker tells the British publication of Justin and Kendall:
"They were seriously flirting and kept going in and out of a photo booth together. There was lots of laughing and teasing and they were taking endless selfies."
And then this bombshell:
"After partying for about two hours, they quietly slipped out of the party together and were seen holding hands."
We can't help but wonder: did Bieber slip something else to Jenner that night, if you know what we mean!
Bieber and Jenner had dinner together this spring and talk that the pair are more than friends has been circulating for months now.
Many believe that Justin's relationship with both Jenner sisters contributed to his split from Selena Gomez earlier this year.
And just how is Gomez feeling about her ex these days? Jealous? Sad? Angry?
"She's disgusted with how he's behaving," an insider tells Hollywood Life. "She's not hurt, she's actually grateful that she's not with him anymore. In her opinion, he's acting out and she would rather have nothing to do with him."
