One Direction star Louis Tomlinson has reportedly named his baby boy Sydney Rain.
The singer and Los Angeles-based stylist Briana Jungwirth welcomed their baby son on Friday.
While the couple are yet to file a birth certificate for their son, they came up with the unusual name together.
"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," a source told The Sun UK. "It's not yet known whether the baby boy will take Briana's surname or Tomlinson."
Writing on Twitter on Saturday, Tomlinson said: "I'm pleased to say my baby son was born yesterday. He is healthy and pretty amazing. I'm very happy!!"

"Daddy daddy cool," he added.
Tomlinson met Jungwirth in 2015 through mutual friends after he and Eleanor Calder, his longtime girlfriend, broke up.
Twitter exploded with memes as 1D fans express their disappointment and shock of the news:
