Louis Tomlinson is set to become a dad, according to reports and frenzied social media speculation.

The Internet was buzzing with a mix of shock, horror and plain confusion from Directioners after People magazine broke the story late yesterday evening.

So who is the mother? It's said to be 23-year-old, LA-based stylist, Briana Jungwirth, who dated Louis back in May (and was often papped next to him on nights out), shortly after he split from his girlfriend of four years, Eleanor Calder.

Louis and Briana are not in a relationship, but are thought to be good friends.

A source told People: ‘Their friendship is extremely strong and they are both really excited about the baby. It’s early days and Briana and the baby’s health are the most important things right now.’

We watch this space for confirmation.
