Kelly Clarkson and Brandon Blackstock celebrate third anniversary

Once upon a time, pop superstar Kelly Clarkson was known as the breakup anthem queen. Her songs rocking and bitter, Clarkson cleverly (and sometimes bluntly) slayed anyone who crossed her path. Rather it be a romantic relationship or a working relationship, her tracks were the epitome of a kiss off. It goes back to 2004 when she released the Grammy winning Breakaway featuring the song "Behind These Hazel Eyes," a track about a relationship gone bad and one that almost didn't make the album. 2007 saw the carryover track "Never Again" for album My December and it was even more scathing and right to the point. Those days however are gone and she's happily married with two children. Kelly Clarkson and husband Brandon Blackstock (Reba McEntire's former step-son) are celebrating three years together (Oct. 20) and are as happy as can be.

Though now in her mid 30s, Clarkson is still a bubbly child at heart who just knows better. She took to her social media including Twitter to post a picture of what young love classically looks like. Carved on a tree, their love remains forever with an arrow stricken heart along with their initials saying, "B + K = LOVE."

Shortly after the couple were wed on Oct. 20, 2013, she released her first holiday album Wrapped in Red produced by Greg Kurstin that included classics as well as new songs, one she wrote for Blackstock ("Winter's Dream"). However, while promoting the album, she had to come clean that she was pregnant with their first child as a couple (Blackstock has two from a previous marriage). The pregnancy was so intense that she was forced to cancel remaining promotional dates and rest. In 2015, Clarkson was performing the autobiographical "Piece by Piece" on stage where she encountered her emotions getting the best of her. It was then she announced she was pregnant with a second child. Remington Alexander was born April 12, 2016.

Clarkson and Blackstock met several years before they began dating, when he was still married. His father, Narvel, has been Clarkson's manager since 2007 just as she released My December. When asked about which performance in her career made her the most nervous? Singing the National Anthem at the Super Bowl in 2012 solely because she didn't want to make mistakes in front of Blackstock who was watching. Fast forward to 2013, Blackstock put a ring on it and joined the engagement and wedding bands together.

While promoting children's book "River Rose and the Magical Lullaby," Clarkson gushes speaking of her children and relationship with Blackstock. Through more than a decade of failed dates, Kelly Clarkson is no longer "Miss Independent."
