Coleen posted a heartfelt message on Twitter today (12 June), telling fans that she and and footballer Wayne are "stronger than ever".
Wayne is currently in Brazil for the FIFA World Cup, which kicks off tonight, and it is thought she will be joining him in the coming days.
Alongside a happy photograph of the couple, Coleen told her followers: "6 years ago today I became Mrs Rooney! Through all the good times & some bad....We are stronger than ever."
Coleen and Wayne met at school and now have two children together, four-year-old Kai and Klay, one. But their relationship hasn't always been smooth running.
In 2010, Wayne found himself embroiled in a cheating scandal after it was revealed that he had slept with two hookers. One of them, who has now given up prostitution, is current Big Brother contestant Helen Wood.
The couple did, however, managed to work through their problems and are now firm in their marriage.
Earlier this week, Coleen and Wayne celebrated another milestone in the Rooney household, as Klay took his first steps!
Posting a sweet picture of her little man on Facebook, Coleen said: "Yay......Klay took five steps today!! On our way! x."
Happy anniversary guys, and good luck on Saturday, Wayne!
