Louis Tomlinson shares photo, name of baby son

It's only been a week, and Louis Tomlinson is already proud to show off his baby boy.

The One Direction crooner posted a photo of his son and introduced him to the world.

"Meet my little lad, Freddie," he wrote on Twitter.

Tomlinson and his friend, Briana Jungwirth, welcomed Freddie last Thursday in Los Angeles.

The singer, 24, and Jungwirth briefly dated in May, though lately he has been linked to Danielle Campbell. Tomlinson and Jungwirth, who is a hairstylist, are good friends.

The One Direction star was reportedly very excited to be a dad, and flew out to Los Angeles for Jungwirth's ultrasounds while he was on tour with One Direction. A source told People that Tomlinson plans to be a "hands-on dad."
