Marvel superstar Sebastian Stan was seen celebrating as he became a father for the first time.
The 43-year-old star was seen welcoming a baby with partner Annabelle Wallis as people reported the couple had chosen to keep details of their newborn private after the birth last month.

The publication was seen confirming how the birth took place on Monday after the duo was seen publicly sharing how they were expecting during a walk in New York in April. This is when Annabelle debuted her baby bump. Reps for Sebastian and Annabelle couldn't be reached for comment at the time.

The news comes during a landmark period in Sebastian's career following awards recognition for a different man and his acclaimed portrayal of Donald Trump in The Apprentice. He even starred recently in Marvel Studios' Thunderbolts after nearly a decade playing Bucky Barnes, who is also known as the Winter Soldier in the Marvel Cinematic Universe, starting with Captain America: The Winter Soldier.
