David and Victoria Beckham's children, Brooklyn, 18, Romeo, 15, Cruz, 12, and six-year-old Harper, were said to be "excited" about having a new cousin in their lives.

A source previously said: "David's kids are excited about having a new cousin, especially Harper."

Joanne once dated David's former England teammate Jermain Defoe, and his former Manchester United co-star Dwight Yorke, who is the father of Katie Price's 15-year-old son Harvey.

Kris previously starred in 'Big Brother' in 2009 and went on to date fellow contestant Sophie Reade, and later 'Hollyoaks' actress Jorgie Porter.

David is already an uncle to his elder sister Lynne's five children.
