Kelly Clarkson took to Twitter on Tuesday to celebrate two landmarks -- having "made a human," and drinking her first glass of wine since giving birth. "I still can't believe I made a human," wrote the 32-year-old singer along with the hashtags: "#topthat #firstglassofwineintenmonths #pump&dump :)" The original "American Idol" winner and her husband Brandon Blackstock welcomed their first daughter, River Rose, on June 12. Eight days later, the singer shared a beautiful snapshot of her baby daughter on social media, calling River the "greatest thing on the planet." The "Because of You" singer is also a stepmother to Blackstock's son and daughter from his previous marriage. The couple has been married since October 2013.
