Amir and Faryal welcomed their daughter today (23 May) and have called her Lamysa, which means 'soft to the touch' in Arabic.
Announcing their exciting news on Twitter, Amir told his followers: "Faryal and I are delighted to announce the birth our first child Lamysa Khan, everyone doing very well, thank you for all your wishes."
The former WBA and IBF lightw-elterweight boxer has since posed for two pictures while cradling his little girl. Alongside them, Amir commented: "Mine and @FaryalxMakhdoom newborn baby LAMYSA. Born on 23rd May 2014 at 4:05am #Blessed."
Amir has also tweeted a photograph of himself with his parents, saying: "Me and mum dad with my newborn baby Lamysa."
In January 2012, Amir announced his engagement to Faryal. The couple met while she was studying political science in New York.
The pair tied-the-knot in a lavish ceremony at the Waldorf Astoria Hotel in Manhattan, which was attended by a 1,000 people, before jetting back to Amir's hometown of Bolton for a second celebration - with a staggering 4,000 guests.
Amir and Faryal announced that they were expecting their first baby together in October last year.
