People magazine confirmed that the couple are now proud parents, with their little one being born on the 1st August. However, we'll have to wait in suspense for further details such as the baby's sex or name, as the couple are staying very private at the moment.
The 35-year-old star, who is best know for her roles in Netflix series Unbreakable Kimmy Schmidt and 2011 comedy hit Bridesmaids, revealed the happy news of her pregnancy during a taping of The Tonight Show Starring Jimmy Fallon in April.
'I have big news, I'm pregnant!' she told the host, and pointed to her growing bump. Jimmy leaned over and said, 'Hi baby!', and then gifted Ellie a tub of Ben & Jerry's The Tonight Dough ice cream to celebrate.

A source told US Weekly that Ellie had kept her pregnancy under wraps while filming the second series of Unbreakable Kimmy Schmidt, confiding only in the show's creator, Tina Fey.
Speaking about their close relationship previously, Ellie said, 'I'll find myself telling her some totally mind-numbing story about laundry and it'll occur to me: Stop wasting her time! She's got books to write and movies to make and lives to change!'

The baby is the first child for both Ellie and husband Michael, who is a writer who has worked on Late Night with Conan O'Brien and MADtv. The pair dated for a few years before marrying in July 2012, with Ellie's co-stars Kristen Wiig and Maya Rudolph from Bridesmaids, which had been released the year before to glowing reviews, in attendance.

'Michael's a delight, as you know, so of course [my parents] like him a lot,' Ellie told Conan O'Brien at the time.
We can't wait to hear what baby name they chose, and hopefully see a no doubt adorable picture soon. Congratulations, Ellie and Michael!
