The couple, who became engaged on Eniko’s 30th birthday, celebrated their third wedding anniversary last August.
In an Instagram post last week, Eniko shared the family’s joy at the gender reveal.
The couple’s first child together, Kenzo Hart, was born in November 2017.
Heaven Hart, 15, and Hendrix Hart, 12, are products of the comedian's first marriage to Torrei Hart .
While Torrei initially alleged that Kevin and Eniko’s relationship began before their marriage ended, Kevin has maintained that he and Torrei were divorced before the start of his new relationship, according to Oprah Magazine.
