Ellie Kemper has given birth.

The 36-year-old actress and her husband Michael Koman - who got married four years ago after a few years of dating - recently welcomed their first child together, PEOPLE reports.

No other details have been revealed.

Ellie announced her pregnancy during a taping of 'The Tonight Show Starring Jimmy Fallon' in April, but up until that point had kept her bump and exciting news under wraps.

She told the host: ''I have big news, I'm pregnant!'' before pointing towards her pretty floral dress.

The funnyman immediately leaned over and said, ''Hi baby'' before gifting her with a pot of Ben & Jerry's ice cream.

Ellie kept her pregnancy hidden from her co-stars while shooting 'Unbreakable Kimmy Schmidt' but did confide in producer Tina Fey as soon as she found out.

She said: ''We had a table read, and my character is supposed to be on a rollercoaster ...

''It was still very early on, but I felt like a pregnant lady on a rollercoaster was not ideal so I had to tell my boss, Tina Fey. She knows every secret. I told her before I told my mom.''

After telling Tina, the pair decided to conceal her pregnancy by telling everyone on set she had suffered a back injury so couldn't go on the rollercoaster - but Ellie found the lie harder to pull off than she expected.

She admitted: ''I could not act like I had a back injury.

''I'm an actress, presumably. It was so [hard]. Someone asked, 'What's wrong?' and words escaped me. I'm like, 'I sprained my spine.' You can't sprain your spine! You can't do that!

''I kept forgetting I had [a back injury] so I kept doing things someone with a back injury can't do. They'd say 'Lunch!' and I'd like leap up and do cartwheels to catering. You're not supposed to do that!''
