During 1D's appearance on Good Morning America on 4 August, host Michael Strahan managed to tease the details out of the 23-year-old by congratulating him on the baby news.

Strahan asked: "Louis, from one father to another, I want to congratulate you on your upcoming fatherhood. So, how are you feeling?" Tomlinson replied: "Obviously it's a really exciting time, so I'm buzzing, thank you." Although there was no mention of the mother, it is believed the singer is expecting the baby with Los Angeles-based stylist Jungwirth.
