Louis Tomlinson 'names son Sydney Rain'

One Direction star Louis Tomlinson has named his son Sydney Rain, according to reports in The Sun.

The 24-year-old popstar, who is from Doncaster, became a father for the first time on Friday with American stylist Briana Jungwirth.

The Sun reports that the pair are yet to file a birth certificate, but the name is expected to be confirmed in the next few days.

Louis is no longer with Briana and it is not known whose surname the baby will take.

On Saturday the star tweeted his delight at the baby's birth.

Louis' grandfather Len Poultson confirmed to ITV News that the baby was welcomed into the world in a Los Angeles hospital.
