A source told Hollywood Life Monday that if Grande did move on, her new beau "will have to be famous and understand her demands and schedule."

"Not to say that anything is brewing, but those are the guys that will be around her for awhile and have the best chance. But to be honest, it's her career that matters now!"

As for her latest flame Big Sean, they also said that the two haven't talked much since calling it quits for good.

"It's over and they are both bitter and busy and don't want to get ahold of each other."

Even though it was said that their split was amicable and they were still close friends, this insider has a different side.

"When they think about each other or talk about each other it's often negative."

Grande and Big Sean have worked on several songs together from Best Mistake to the newest collaboration Research (off of Big Sean's newest album Dark Sky Paradise). They dated for about eight months before breaking up.
