Kelly Clarkson has given birth to her first child. On Saturday, the proud mom took to Twitter to share her and husband Brandon Blackstock's big news: "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!!" In November, Kelly announced her pregnancy on Twitter just before the holidays. "I'm pregnant!!! Brandon and I are so excited! Best early Christmas present ever," she wrote. The singer and American Idol alum debuted her growing baby bump in April, stepping out for a family day in a festive top adorned with a giant bow. Congratulations, Kelly and Brandon!
