Over the weekend, Mackenzie Douthit, star of “Teen Mom 3” on MTV, revealed the gender of her impending bundle of joy — a little girl. She posted the above video on Instagram, which shows her Josh McKee slicing into a cake that is pink on the inside, indicating a baby girl is on the way.

Douthit tweets of the big news, “Josh cannot stop smiling. He’s always wanted a little princess to look after. … Now josh is calling all his rodeo friends to tell them #cutedadtweet.”

The couple, high school sweethearts who got married just one month ago, are parents to 2-year-old Gannon. “Teen Mom 3” airs Monday nights at 10 p.m. ET/PT on MTV.
