The couple, who got married in 2009, also has a four-year-old boy Azaan together.
"Yeah he has become a father to a baby girl this morning. Second child," his representative confirmed to IANS.
Ali made his Bollywood debut in 2010 with "Tere Bin Laden" and went on to do films like "Mere Brother Ki Dulhan", "Chashme Baddoor" and was recently seen in "Kill Dil" also starring Parineeti Chopra, Ranveer Singh and Govinda.
Ali, who has appeared in several commercials in Pakistan, has also acted in TV serials "Lunda-Bazar", "Kanch Ke Par" and teenage sitcom "Kollege Jeans" in his home country.
Not only this, he has also paid a musical tribute to the Peshawar attack victims with his new single "Urein ge" earlier this month.
The world was left shocked in December last year by the gruesome killing of 145 people, including 132 children in an attack by a terrorist group on an army-run school in the Pakistani city of Peshawar.
