Louis Tomlinson's mother has given birth to twins.

The One Direction singer and his family are celebrating after his mother Johanna Poulston, 40, welcomed son Ernest and daughter Doris into the world on Monday (10.02.14).

The 22-year-old heartthrob, who also has four sisters, Lottie and Felicite, and another set of twins, Phoebe and Daisy, rushed to be with his family after the new babies were born prematurely at Barnsley Hospital in South Yorkshire.

A source told The Sun newspaper: ''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.''

The new babies were delivered close to Louis' home town of Doncaster and Johanna and her son and daughter are said to be healthy and doing well.

A spokesman for Louis also said: ''Daniel and Johanna are pleased to welcome twins -- a boy Ernest Rupert Atholl Deakin, 5 lbs 12oz, and a girl Doris Poppet Deakin, 4lbs 11oz.

''Daniel and Johanna would like to thank Barnsley Hospital, their special care unit, the Embrace team and Jessops special care unit. All the family are delighted.''

Johanna has been with the twins' father, Daniel Deakin, 30, for two years after she split from Louis' dad Mark Tomlinson when he auditioned for 'The X Factor' in 2010.

Johanna and Daniel got engaged in March last year but are yet to set a date for the wedding.

Meanwhile, Louis and his One Direction bandmates - Niall Horan, Liam Payne, Zayn Malik and Harry Styles - are on a three-month break after a hectic touring schedule but are set to appear at the BRIT Awards in London next week.
