Jesse Eisenberg has become a father for the first time.

The 'Batman v Superman: Dawn of Justice' star is thought to have welcomed a child with his long term partner Anna Strout after the pair were seen out and about in New York with their baby on Monday (03.04.17), E! News reports.

Jesse has kept quite private about his 14-year relationship with Anna and had previously admitted that he loves surrounding himself with people who ''want to help other people''.

He said previously: ''I find people who want to help other people to be the most interesting. I come from a family of teachers, and my friends are teachers, often times in very difficult school situations. My job is so selfish and focused on my own vanity that I like to surround myself with people who are actually helping people throughout their day.''

Jesse and Anna dated from 2002 to 2012 before deciding to take a break whilst Jesse focused on his career. And then the actor spent four months volunteering for a domestic violence shelter in Bloomington, Indiana. It was whilst volunteering that Jesse was put back in touch with Anna, as her mother is the shelter's executive director.

Speaking about his work with the shelter, he remained coy.

He said: ''I was there for, like, personal reasons. For reasons I don't want to bring up in an interview.''
