Pop star Kelly Clarkson accepted the ALS Ice Bucket Challenge this week, making her first appearance since giving birth to her daughter River Rose with husband Brandon Blackstock.

Kelly Clarkson Takes ALS Ice Bucket Challenge

Clarkson and Blackstock teamed up to do the ALS Ice Bucket Challenge after getting nominated a number of times. “Hey this is Kelly Clarkson! I’m really nervous about this,” the “Stronger” singer admitted. “I was nominated by a ton of mean people to do the ALS Ice Bucket challenge and we’ve been trying to do it, but we’re just nervous about it.”

Clarkson was hesitant to lift the large bucket over her head, saying, "I hope I can lift the bucket because it's really heavy." Eventually, both Clarkson and Blackstock completed the challenge. After getting doused with the icy water, Clarkson rushed out the camera frame yelling about how cold the water was.

Clarkson and Blackstock welcomed River Rose two months ago on June 12. Since then, the American Idol alum has gushed about her daughter on Twitter.
