'Teen Mom' Star Catelynn Lowell Shows Off Baby Bump at 33 Weeks Pregnant! [PHOTOS]

MTV reality star Catelynn Lowell of Teen Mom and 16 & Pregnant showed off her second pregnancy baby bump via Instagram last Friday, Nov. 21.

"Baby girl almost 33 weeks," Lowell captioned a baby bump selfie.

As MStars News reported back in August, Catelynn and longtime boyfriend Tyler Baltierra took to their Instagram to reveal the gender of their baby, a girl!

The couple had a now very popular gender reveal party for their family and friends which included a piñata that was either stuffed with blue or pink confetti, and to their guests surprise, pink confetti came streaming out!

This will be the second child for the couple. They were the original cast members documented on MTV's 16 & Pregnant as they opted to place their daughter Carly up for adoption in May 2009.

The couple has been through some ups and downs, as seen on MTV. Catelynn and Tyler also had a stint on VH1 Couples Therapy where they documented their trust issues, adoption choice and derailed wedding plans.

Currently it seems as though the two are happy as Catelynn has not only shown off her baby bump, but also her love for Tyler. "A love like ours can never be broken," she captioned an Instagram photo of November 23.

As MStars News has also reported back in September, the couple is hoping that their daughter can grow up with the couples first child – now five and adopted.

"Our child [will grow up] with Carly around her," Catelynn revealed during an interview with In Touch. "My hope is that they'll have a great relationship one day. They're sisters."
