The Ukraine international's wife Vlada Sedan gave birth to a baby girl in a Miami hospital on Sunday.
Oleks Zinchenko has welcomed his first child with his wife Vlada Sedan
The Manchester City star was on FaceTime with his other-half in hospital
Delighted wing-back Zinchenko posted a picture of Vlada and the new arrival on social media.
The 24-year-old wrote: "Dear, thank you! Vlada Sedan, you are my life! 08/01/2021."
The couple married last August - but Zinchenko broke off from his wedding issue a statement on his wife's behalf apologising for her reaction to a 3-1 defeat to Lyon in 2020.
The baby's arrival caps off a triumphant 12 months for Zinchenko, who joined City in 2016.
He helped Pep Guardiola's side win the Premier League and Carabao Cup, and reach the Champions League final.
The 44-cap international also shone in Ukraine's Euro 2020 campaign before their 4-0 quarter-final loss to England last month.
Zinchenko returned to action for City on Saturday, coming on as a sub in a 4-0 friendly win over Barnsley.
He has made 100 appearances, scoring two goals, since swapping Russian club Ufa for the Etihad in a £1.7million deal.
Zinchenko proposed to Sedan inside the 70,000-capacity Olympic Stadium in Kiev in front of a heart-shaped display of red roses.
There were rumours the pair were dating after he planted a kiss on her face on live TV following Ukraine's 5-0 win over Serbia back in 2019.
