'Teen Mom 2' Leah Messer Pregnant With Her Third Child? But, Who's The Daddy?

After filing for divorce from her husband Corey Simms, Leah was seen shopping for a home pregnancy test! But is Corey the father?

It’s only been two weeks since Teen Mom 2 stars Leah Messer and Corey Simms called it quits on their six-month marriage, but it sounds like there’s already more drama ensuing — this time it’s baby drama!

Leah, 19, was seen at a Target store near her home on April 22 with a pal, shopping for baby supplies and a home pregnancy test. “She looked very worried,” a witness tells In Touch. “She left her friend behind when she went to the aisle with the pregnancy tests, telling her she’d meet her in the car.”

If she is pregnant with Corey’s baby, Leah will be left to fend for herself and her 16-month-old twins Aleeah and Aliannah, due to the fact that her ex reportedly has drained their joint bank account. Not to mention Leah has officially moved out of their home and is scrambling to baby-proof her new place so the twins can visit.

“Leah’s biggest nightmare is getting pregnant with no way to care for her babies and no money,” shares a friend. “As hard as it was before, it’s going to be even harder now.”

But is Corey the father? Leah has recently reunited with her former flame, Robbie Kidd, who she dated for three years prior to getting pregnant with Corey. “Leah was my girl longer than anyone’s, including Corey, and I’ve always looked at her as the one that got away,” Robbie tells In Touch. “In my perfect world, we would be back together, and I’d help her raise the girls.”

So if Leah is pregnant with Corey’s child, Robbie’s dream of rekindling his past love may be in jeopardy. Will Leah rethink the divorce?
