Ever since Justin Bieber got unfollowed by his on-again, off-again girlfriend Selena Gomez, he's been switching things up a bit. Not only is he hanging with Kylie Jenner, who Sel is supposedly feuding with, but he's been spending a lot of time with another girl, too — 18-year-old model Yovanna Ventura.

The two have been posting numerous pictures together on Instagram, and Justin looks like he's really digging the Miami Senior High School student. Although he claims they're just friends in the caption of one of his pictures with her, E! News is reporting things might already be getting serious.

Justin and Yovanna were recently spotted on the Venice Beach boardwalk, and onlookers said they were acting like a couple. They even took a ride on a rickshaw, where Justin supposedly had his hand on her leg the entire time!

"Justin seemed very chill and happy," the source said. "Justin wanted to meet her. He sought her out. It hasn't been too hot and heavy, but they have been hanging out a lot. Their relationship is blossoming. I wouldn't be surprised if they have now started dating."

So how did they meet? Evidently Justin reached out in late March and they've been talking ever since.

"In early April, when he came to Miami they hung out together for that weekend while he was recording in the studio," the source added. "It was for a couple of days, the weekend. They were getting to know each other."

Since Justin also hung out with Selena while he was working on his music that weekend, it's hard to say what's going through his mind. But one thing's for sure — he definitely needs to choose. Does he go back to Selena or try things out with his new girl?
