Farrah Abraham may be keeping her possible pregnancy under wraps – but she’s putting her bump on full display! The Teen Mom OG star showed off her burgeoning belly in a barely there bikini.

Abraham showed off her stomach in a revealing green and gold bathing suit over Instagram.

As Breaking Celebrity News readers know, Abraham sparked pregnancy rumors when she was spotted with a bump while on vacation with her on-again, off-again boyfriend, Simon Saran.

“She’s not pregnant,” he told Breaking Celebrity News at the time. “I believe she had too much Dr. Pepper to drink for breakfast that left her looking bloated.”

But when her bump was spotted again in a sports bra, Saran changed his tune!

“Yes, she’s 26 and pregnant,” he told Breaking Celebrity News, perhaps jokingly.

Abraham has yet to confirm the rumors.

This would be the MTV star's second child, as she’s mother to daughter Sophia, 8, with ex-boyfriend Derek Underwood. Underwood tragically died in a car accident when Abraham was pregnant.

Abraham wouldn’t be the only pregnant Teen Mom star, as Teen Mom 2’s Kailyn Lowry is expecting her third child in only a few weeks with ex-boyfriend Chris Lopez. She is also mother to Isaac with ex-boyfriend Jo Rivera, and Lincoln with ex-husband Javi Marroquin.

The newest Teen Mom 2 star, Briana DeJesus, is also due to give birth in a few weeks. She is mother to daughter Nova with baby daddy Devoin Austin.
