Rumors circulated that Meghan Trainor is dating Nick Jonas' personal assistant Cory Anderson, ET Online reported.

The "All about that Bass" singer and Anderson have been seeing each other since November according to reports.

ET Online also reported that the 2014 breakout star brought Anderson to an event at Philymack studios back in November.

Yet, a source told Us Weekly that it is all a joke and that the 21-year-old Grammy nominee is not seriously dating Cory.

"Andersen was on the Jingle Ball tour with Nick, as was Meghan...She was also in the trailer next to his 'Dancing with the Stars' taping, but the only time she was around was when she could just come say 'Hi' to Nick - totally normal like any other artist," the insider said.

"They've met and been cool with each other but that's all it is right now."

Daily Mail reported that back in September, Meghan talked publicly about getting dumped by her boyfriend just around the time "All about that Bass" gained popularity in Canada, Denmark, Australia and the U.S.

She said at the time, "I'm looking for a good person. Or someone who doesn't start dating someone else while they're dating me, you know what I'm saying?"

Trainor talked about how when she got back from a trip, she found out that her boyfriend was dating someone else. Her ex-boyfriend started to date another girl the day she left for a hectic tour.

"He just couldn't date a popstar, man. It's hard," she said about the split.

The news of her breakup came at the time when her "All about that Bass" video gained over 70 million views on YouTube.

Just last month, Jennifer Lopez gave the pop star some relationship advice, according to USA Today. J. Lo told her to be very picky and to know her worth.
