Beachside bump! Teen Mom star Catelynn Lowell has no problem hitting the town while pregnant. The 22-year-old confirmed her second pregnancy last month, and is now five months along. 

On Monday, Sept. 8, she posted a picture to Instagram with her stepsister Amber Lowell while visiting her sis in Florida. 

“Mee and my sista #Auntie @amberlowell_,” she captioned the picture of Amber cradling her baby bump. 

This is the second child for Lowell and boyfriend Tyler Baltierra, who welcomed daughter Carly in 2009 on MTV’s 16 and Pregnant before giving the little girl up for adoption. 

The couple is expecting another little girl, and plan to keep the baby. On Aug. 31, Lowell posted a baby bump mirror selfie, writing, “Baby girl.” 

Originally Baltierra was set to wed Lowell in July 2013, but after Baltierra decided he wasn’t ready to get married on VH1’s Couples Therapy, the couple called off the wedding and is yet to announce any future plans to marry. 

After MTV aired her special Being Catelynn, Us Weekly learned that the network is bringing back original Teen Mom cast members Lowell, Maci Bookout, and Amber Portwood for a new season in 2015.
