Madonna and Guy Ritchie reunited to celebrate their son Rocco's 15th birthday. The former husband and wife - who split in 2008 - were both in attendance at the teenager's birthday party. According to the Daily Mirror newspaper, the family sang 'Happy Birthday' to Rocco and presented him with a cake during the celebrations. The 'Rebel Heart' singer and the film director married in December 2000, four months after Madonna gave birth to Rocco John Ritchie. After their marriage broke down Guy reportedly received between £50 million and £60 million from the divorce settlement with the couple agreeing to co-parent the children, splitting their time between the UK and US. The celebratory event was held just a fortnight after Guy tied the knot with Jacqui Ainsley, the mother of his three youngest children at their home in Wiltshire, England.
