They're seeing pink — again! Pregnant Teen Mom star Catelynn Lowell and Tyler Baltierra found out that they are expecting a second baby girl during a gender reveal party on Saturday, Aug. 16.
The couple, both 22, celebrated with family and friends at what appeared to be a park. Benches, dinnerware and streamers were decorated in both pink giraffes and blue whales before popping a pinata to reveal pink confetti.
"Today is the day! We finally get to find out if we will have a son or a daughter #Anticipation #IsKillingMe," Balitierra wrote via Instagram before the bash.
Lowell later posted a video of the reality stars throwing the baby carriage pinata in the air. "It's a…" Lowell teased.
"#it'sofficial #4months @tylerbaltierramtv," she wrote via Instagram on Aug. 6, along with a picture cradling her growing baby bump.
Lowell and Baltierra previously placed their daughter Carly, now 5, for adoption while starring on MTV's 16 and Pregnant in 2009. (As previously reported, Lowell and former costars Maci Bookout and Amber Portwood will be returning for another round of Teen Mom in 2015.)
