Selena Gomez Boyfriend 2014: Taylor Swift Jealous Over Justin Bieber Date? Source Said She Won’t Be Able To Trust Her After Hanging Out With ‘Heartbreaker’ Singer

Selena Gomez recently went on a Segway date with Justin Bieber and a source close to Taylor Swift revealed she may be jealous and feeling untrustworthy.

"Once Taylor finds out that Selena is hanging out with Justin she will be very mad," a source told HollywoodLife.com.

"This is exactly what Selena has told Taylor all along that she would not do, and now that she has, [it] will show Taylor that she can't trust Selena."

Selena Gomez is rumored to have gotten back together with ex-boyfriend Justin Bieber and talking to Romeo Miller, new information reveals.

An eyewitness told In Touch magazine that the couple was spotted having a good time riding Segways in Calabasas on Thursday.

"Justin and his friend were ahead while Selena trailed behind his security was blocking the road and it held up traffic," the source told In Touch magazine.

"They looked like they were having a really good time and having so much fun. Obviously the two are talking again but they haven't been seen in the neighborhood together before."

Selena Gomez was spotted in one of Romeo Miller's Instagram pictures wearing his sweater with a romantic caption just days before.

"I live for the nights that I can't remember with the people that I won't forget. #romeeverything," he captioned the photo.

There is no official confirmation on whether they are dating.
