Kelly Clarkson made a surprise announcement during a concert at the Staples Center in Los Angeles Wednesday: She's pregnant!

The singer told the crowd that she wasn't planning to share the news yet, but blurted it out when she became emotional while introducing her song "Piece By Piece."

"I'm totally pregnant. I'm having a really hard time," she said through tears.

Later, she explained: "That was not how I wanted to announce that. ... I just don't want you to think I'm on pills or drunk."

This will be the second child for Clarkson and her husband Brandon Blackstock, joining big sister River Rose, who turned 1 in June. The couple got married in October 2013. Blackstock also has a son and a daughter from a previous marriage.

After she finished singing "Piece By Piece" Wednesday, Clarkson, 33, apologized to Blackstock for her impromptu announcement. But she also noted that the fact she hadn't vomited at all that day was "a freakin' win."
