Coleen Rooney has paid tribute to her late sister Rosie.

Alongside a photograph of her with Rosie, taken in 2008 at her wedding, Coleen wrote on Twitter: "Happy 18th Birthday to our very own angel! Love you Rosie xxx (sic)."

Rosie, who Coleen's parents Tony and Colette McLoughlin adopted as a baby, sadly passed away four years ago after she lost her battle with the rare brain disorder Rett Syndrome.

After Rosie's tragic death, Coleen and her husband Wayne - who is captain of the England soccer team - made it their mission to raise funds for sick and disabled children.

The brunette beauty even made a television documentary to raise awareness of children's hospices; such as the Claire House in Liverpool, where Rosie stayed two nights a week.

Meanwhile, Rosie's 18th birthday comes less than two weeks after Coleen and Wayne - who already have sons Kai, six, and Klay, two - welcomed their third child Kit into the world.

Taking to her Twitter on a more positive note 11 days ago, Coleen said: "Our gorgeous little Boy arrived today!! Kit Joseph Rooney .... 8Ib 1oz. We are all over the moon!! (sic)"
