The One Direction star's tweet has hit the headlines again today following the surprise news that he's reportedly expecting a baby with his stylist friend Briana Jungwirth.
News broke in the US overnight that US-based stylist Briana is pregnant with the singer's first child, although reps for Louis have not commented on the claims.
Can't believe I'm going to be a Dad! Wow!!— Louis Tomlinson (@Louis_Tomlinson) April 1, 2012
The internet has gone crazy with memes and fan reactions, with plenty pulling up Louis' old tweet from 1 April 2012.
He had posted an April Fool's joke reading: "Can't believe I'm going to be a Dad! Wow!!"
Louis was dating long-time girlfriend Eleanor Calder at the time. They split earlier this year. It's thought he was introduced to Briana via mutual friends in May and although they're not in a relationship, they remained friends and he will support her throughout the pregnancy.
