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 and were joined by their second son David, nine, and Guy's new wife, Jacqui Ainsley, 43.

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 46-year-old film director married in December 2000, four months after the 56-year-old icon 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 the mother of his three youngest children - Rafael, three, Rivka, two, and 13-month-old Levi - at their lavish home in Wiltshire, England.

The couple had been dating since April 2010 after meeting at a friend's party the year before.
