Kelly Clarkson now has her own Miss Independent. The American Idol winner gave birth to River Rose on Thursday. On Saturday, she shared the news on Twitter, an appropriate messenger considering she used the social network to announce both her pregnancy in November and the sex of her baby in January. Using enough emoticons to convey her true pleasure with motherhood, Clarkson tweeted "Thank you everyone for all of your well wishes! Brandon and I are on cloud 9!! :).” This is the first child for the “Stronger” singer. Last year, she married talent manager Bandon Blackstock, who happens to be the stepson of fellow country singer Reba McEntire. He has two children from a previous marriage.
