Louis Tomlinson has become a brother again after his mum gave birth to twins Ernest and Doris.
The One Direction star, 22, was in the UK when 40-year-old midwife Johanna Poulston's baby boy and girl were born prematurely.
A source told The Sun: "Louis is over the moon. He met Ernest and Doris and fell in love with them.
"Family is massively important to him so he was made up that he was not abroad and was able to meet them so soon after they were born.
"His sisters mean the world to him so he's delighted to have two more siblings to spoil."
Louis already has four younger sisters - twins Phoebe and Daisy and siblings Lottie and Felicite.
The babies were born at Barnsley Hospital in South Yorkshire.
Johanna is reported to have split from Louis' father, Mark Tomlinson, at the same time as Louis was auditioning for The X Factor in 2010.
She has been with the new twins' father, Daniel Deakin, 30, for two years.
