First-time father Stephen Amell has proudly shared a photo of his baby girl. The photo, which was uploaded on his Facebook on Saturday, October 19, shows him holding his newborn daughter. He can be seen pointing to a TV screen while baby Mavi is asleep.

The baby is wrapped in white blanket. She also wears a white hat. "She came just in time for Amell Wednesdays," the "Arrow" actor captioned the photo.

Stephen and his model girlfriend Cassandra Jean exchanged vows in an intimate ceremony on Christmas Day of 2012 in the Caribbean. The ceremony reportedly was officiated by the couple's good friend. They later flew to St. Bart's to spend the new year together.

In June, the pair confirmed that they were expecting their first child. The former contestant of "America's Next Top Model" showed off her small baby bump at the Monte Carlo TV Festival opening, telling PEOPLE that she had not felt any craving. "I'm excited - no I'm not excited, I'm very excited! I'm sure that nervous energy will accompany that eventually, but only in a positive way," her husband said of the pregnancy.

Cassandra gave birth to the couple's first child on Tuesday, October 15. "Mavi Alexandra Jean Amell was born on Tuesday afternoon (October 15). Everyone is happy and healthy," a representative for Stephen told JustJared.
