Teen Mom 2′s Jo Rivera has just released his debut rap single “Unthinkable Remix” and his baby mama Kailyn Lowry, says his so-called rap career is just that.  Unthinkable.

Rivera has been attempting to break out as the rap artist N.I.C.K B since he released a YouTube video of himself in the studio two months ago.

Rivera’s ex, Lowry has immediately lashed out against his attempts to become a mainstream rap artist, telling TMZ:

“I think he has his priorities mixed up right now. He should be spending quality time with his son while he’s not working.”

And why exactly does Lowry want their son Issac spending time with his dad?  The 19-year-old was just arrested in February for being under the influence of marijuana while driving in Warren County, PA and tried to get out of trouble by dropping the Teen Mom card to the police.  Nice try Jo; I doubt the Boys in Blue are up on your reality TV “career”.

In his music video, reportedly filmed in a New Jersey Hampton Inn, N.I.C.K B raps over Alicia Key’s single Unthinkable.  That’s right Jo, don’t stress yourself out coming up with your own original song, just ruin a perfectly good one.
