Chelsea owner Roman Abramovich has reportedly welcomed his seventh child into his family with girlfriend Dasha Zhukova.

The Russian billionaire is believed to have become a father to a baby girl named Leah Lou, who was born at the Presbyterian hospital in New York City last Monday.

It has been reported by RIA Novosti that Abramovich, who did not plan for his daughter to be born in the US, was present at the birth, according to the Daily Mail.

The 46-year-old already has son Aaron Alexander with Zhukova as well as five other children with ex-wife Irina Vyacheslavovna.
