Clarkson has kept a low profile ever since giving birth to her first daughter with Blackstock, River Rose, in June. The short clip is probably the most air time the singer has gotten since.
"We've been trying to do it, but we're just nervous about it!" Clarkson says in the beginning of the clip as she paces back and forth on a brick.
After conjuring some courage the singer and Blackstock emptied their matching buckets over their heads and Clarkson can be seen yelling and running away. The couple nominated several friends for the challenge including the singer's manager Narvel Blackstock.
