This beautiful, super-competitive reality star is pregnant with her first child. The baby is due on her own 30th birthday, January 30. She shared this photo on September 20, showing off her "21 week baby bump."

Who is she? It's Survivor winner Kim Spradlin! The San Antonio, Texas bridal shop owner entered Survivor: One World on the heels of a difficult divorce, but life has turned around for her big-time.

Kim dominated her 2012 season, winning $1 million and the title of Player of the Season. Survivor villain Russell Hantz declared Kim his "favorite all-around player ... socially, strategically and physically a beast! She belongs with the best!"

In March 2013, Kim married her boyfriend Bryan Wolfe in a "casual, boho-chic" wedding in Cabo, attended by fellow Survivor castmates Alicia Rosa and Kat Edorsson. (Kat returned for the new Survivor: Blood vs. Water season that just started last week.)

Back in July, when announcing her pregnancy news, Kim gave People an update on how it was going. “Now that I’m not vomiting every half hour, I really am thrilled,” she joked. “No, but seriously, we’re ecstatic!”

So far, so good! Congrats again to the growing family.
