It's going to be a boy for Kelly Clarkson and her husband Brandon Blackstock. Two months after revealing she was pregnant, the singer shared an adorable gender-reveal photo with fans on Instagram.

"In other news," Clarkson writes, "River's gonna have a little baby brother. #Itsaboy We're so excited!"

River is the couple's daughter, born in January 2014. Clarkson's first pregnancy was very difficult and filled with morning sickness. It's not clear if pregnancy-related illnesses are what led to the doctored-ordered vocal rest that's forced her to cancel her remaining Piece by Piece Tour dates. She made that announcement in September, scrapping 16 shows scheduled for Canada and Europe.

Clarkson and the 38-year-old Blackstock married in Oct. 2013. He has two kids from a previous marriage, and the pending little boy will be his second. The singer revealed the news that she was expecting in a rather impromptu fashion this summer. During a concert in Los Angeles, she just let the news slip.

The singer's greatest country success has come from duets with Reba McEntire ("Because of You") and Vince Gill ("Don't Rush"). In 2013 she also released a solo single called "Tie It Up."
