The couple, who were married in October of last year, welcomed daughter River Rose on June 12th. Clarkson shared the happy news via Twitter, saying, “Our baby girl River Rose Blackstock arrived on June 12th! Thank you everyone for all of your well wishes! Brandon and I are on cloud 9!! :)” River is the first child for Clarkson but the third for Blackstock, who has two children — Seth and Savannah — from his previous marriage.
