One Direction's Louis Tomlinson and stylist Briana Jungwirth have officially welcomed their first child. "I'm pleased to say my baby son was born yesterday :)," the 24-year-old singer tweeted Saturday morning, confirming reports that circulated on Friday. "He is healthy and pretty amazing :) I'm very happy!!" No baby names as of this writing. 

Tomlinson followed with two more enthusiastic tweets: one spree of smiley faces another one reading "Daddy daddy cool" with a headphones emoticon. (Was that a reference to Boney M.'s 1976 disco staple "Daddy Cool"?)

Harry Styles seemingly celebrated by tweeting "flowers all round" early this morning. (It's also possible he'd recently visited a botanical garden.) 

Tomlinson is the first One Direction member to become a father. The singer confirmed the news last year during a slightly awkward moment on Good Morning America. Congratulated on his impending fatherhood, he responded, "Thank you, yeah, obviously it's a very exciting time, so, err, I'm buzzing, thank you."
