Is Leah PREGNANT? Messer Tells All About Baby Number 4

Say what?! Leah Messer sent fans into a frenzy as she opened up about baby number four!

The MTV star had a fan tweet a photo of her where she seems to be holding a positive pregnancy test and questioned if she was REALLY expecting her fourth child.

The caption read, "Is it just me or does this color Lipsense matches these two pink lines?? #MomOfFOur #LipsenseByLeah #Coming2018."

She wrote, "Wtf is this! #definiteNO!"

In the tweet, the fan also included the ORIGINAL image of Leah holding a Lipsense product. Tricky, tricky!

The reality star has three daughters from her two ex-husbands, Corey Simms and Jeremy Calvert.
