Brazil's Ronaldo to take paternity test

Brazilian football star Ronaldo will undergo a paternity test to determine whether a five-year-old boy living in Singapore is his fourth child.

The 34-year-old tweeted that he met the 'beautiful, polite' lad called Alex on Sunday and 'will take on the responsibilities and pleasures' of fatherhood if tests are positive', reports the Sun.

Alex's mother Michele Umezu supposedly met Ronaldo in Tokyo in 2002 when the athlete was there with his then club Real Madrid and got pregnant.

The striker already has three children -- a 10-year-old son with his ex, and two younger daughters, one aged one year and the other eight months, with his wife Bia.
