It sounds like Kendall Jenner and Justin Bieber might be more than just friends.

Jenner wasn’t shy about hanging with Justin in Ibiza, after posting a cuddly party pic with the singer on Instagram.

Now, a source tells The Sun that they were “inseparable most of the night.”

The insider explained, “As soon as Justin arrived he made a beeline for Kendall the moment he spotted her,” the source told the publication. “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.”
