Louis Tomlinson from One Direction has become a father

The 24-year-old singer and his ex-girlfriend Briana Jungwirth welcomed the couple’s first child into the world in Los Angeles on Friday and the One Direction star has taken to his Twitter account yesterday (23.01.16) to confirm the news with fans and share his delight in having a "healthy and pretty amazing" baby boy.

Louis wrote: "I'm pleased to say my baby son was born yesterday :) He is healthy and pretty amazing :) I'm very happy! (sic)”

Just minutes after his first tweet the excited new dad posted the lyrics to Boney M.’s 1976 popular hit 'Daddy Cool' and wrote: “Daddy Daddy cool” and soon after, followed it up with a string of smiley emojis.

Pictures of the little tot have yet to be share, but the couple has decided on a moniker for the baby, though it is not yet clear whose surname the baby will take.

A source told The Sun on Sunday newspaper: "Louis and Briana are yet to file a birth certificate but they've agreed on the name Sydney Rain. It will be rubber-stamped in the next five days.

"It's not yet known whether the baby boy will take Briana's surname or Tomlinson."

Messages of congratulations have started to flood in for Louis and 23-year-old Briana.

The singer's band-mate Harry Styles wrote on Twitter today: "Flowers all round."

And the social networking site went into meltdown on Friday (22.01.16) after the arrival was first reported, when within a matter of minutes, #WelcomeBabyTomlinson was trending and fans worldwide offered their congratulations to the One Direction star.
