Kelly Clarkson has decided to pull the plug on her marriage to Brandon Blackstock. The 38-year-old talk show host has filed for divorce after almost seven years of marriage. The "Since You've Been Gone" singer filed in Los Angeles court last week on June 4, according to documents obtained by The Blast. Kelly Clarkson and Brandon Blackstock, who said "I do" in 2013, have two children together -- five-year-old daughter River Rose and four-year-old son Remington Alexander. It's interesting timing considering the duo recently put their family home on the market.
