Justin Bieber Gets Flirty with Ariana Grande's Instagram: Starlet, BF Ricky Alvarez Not Happy

Justin Bieber commented on a flirtatious video posted by Ariana Grande, calling the pop star "hot." The remark did not go over well with the starlet or her back-up dancer boyfriend, Ricky Alvarez. She even appeared to refer to Bieber as "Satan" in an online post after her Instagram photo went up.

Grande and Bieber have been friends since touring together on his 2013 Believe Tour, but it appears they are no longer very close. That fact is pretty obvious after Ariana Grande posted a cute video to her Instagram account. Grande is shown pouting and giving a kiss, with a bubble and pop sound added.

Fans posted comments on how adorable she looked and Bieber also commented on her sexy post.

Grande’s boyfriend Alvarez responded to Bieber's comments, tweeting, "keep looking player… I already told you she does."

In a cryptic tweet posted the same day, Grande wrote:

It's possible Grande may be trying to avoid issues in her relationship. Her former boyfriend Big Sean was not happy when Bieber got handsy with Grande during a performance.

In August, a source told E! News of Ariana's romance with her back-up dancer, "She and Ricky have gotten pretty close and they are officially a couple. They are keeping their relationship on the down low though and trying to be as private as they can."
