Justin Bieber And Selena Gomez Back Together: ‘Heartbreaker’ Crooner Unfollows Rumored Ex Yovanna Ventura On Instagram, Jelena Now Living In?

Justin Bieber and Selena Gomez appear to be taking their relationship into the next level. The "Baby" singer reportedly asked the brunette beauty to move in with him and while Gomez agreed, she still opted to have a back-up plan.

 "Selena and Justin are a hundred percent together right now. He's asked her to move in with him and she couldn't be happier. She's still being cautious. She's not going to give up her place, that way, if anything goes wrong or if she decides she needs some space, she'll have her own spot to go out to. But, officially, she's going to be living with him. It's a huge step," claimed one insider to Hollywood Life.

To prove that he's trying to change, the Canadian crooner reportedly unfollowed Yovanna Ventura on Instagram, one of his rumored ex-girlfriends. Bieber met fitness model Ventura on Instagram, E! News reports claim.

Bieber is reportedly trying to win back the "Montecarlo" star's trust that he even promised him one thing - fidelity.

"Selena trusts him. She had to let go of her jealousy and stop worrying about other girls. He's promised her that she's the only one, and she believes him. Since they got back together, he hasn't given her any reason to worry - so, she's not going to," claimed the source to the publication.

Justin Bieber and Selena Gomez were recently spotted in Las Vegas after watching Floyd Mayweather Jr.'s fight with Marcos Maidana. Bieber also rented out one of Lucky Strike's rooms for the birthday of his childhood pal, Ryan Butler. During the celebration, one E! News insider claims that Bieber was "seen kissing and flirting" with the "Wizards of Waverly Place" actress.
