Baby No. 2 is on the way for Melissa Rycroft and Tye Strickland.

The "Bachelor" alumna and "Dancing with the Stars: All-Stars" winner announced the news Tuesday with a family photo on Instagram.

"Sooo...It's official, the Strickland Family is growing by one next Spring!" she wrote. "Ava is so excited to be promoted to Big Sister!! We are so excited for our new little addition!!"

The TV personality also announced the happy news on Twitter, writing, "Clearly excited to share our big news!!! A new little Strickland will debut this fall!" She then quickly added, "Oops....clearly not due this FALL! I meant SPRING. (Pregnancy brain at work!)"

Rycroft, 30, and Strickland, who married in 2009, welcomed daughter Ava in February 2011.

"It's just fun, watching her become a little person with a personality and her likes and dislikes," she told CBSNews.com of her daughter earlier this year. " It's really fun watching her grow up."
