ASHLEY Olsen has given birth to her first child with her husband, Louis Eisner.
According to TMZ, the couple secretly gave birth to their son, Otto, a few months ago in New York.
Fans were left stunned by the birth as they took to the X platform to share their reactions.
"Wow, I had no idea she was pregnant! Congratulations Ashley!" one person wrote.
"Little Michelle is having kids. I’m old," another joked referring to Ashley's famous character- along with sister Mary-Kate- Michelle Tanner.

A follower added: "Now it's a full house!"
The Full House alum, 37, and her husband- who tied the knot in December 2022- have kept their relationship mostly private, and it appears any news of the actress being pregnant was kept tight-lipped.
Ashley, along with her famous twin sister Mary-Kate, have both mainly stayed out of the spotlight ever since taking the world by storm as child actors on Full House.
“We were raised to be discreet people,” Mary-Kate once said in a rare interview with i-D magazine last year.
At the time, Ashley opened up about her fashion line with Mary-Kate, The Row, revealing they originally wanted to keep their names away from the brand.
"We didn't want to be in front of it, we didn't necessarily even want to let people know it was us," she shared. "It was really about the product, to the point where we were like: Who could we get to front this so that we don't have to?"
The ultra-famous siblings have been behind the scenes for years, a big change from their childhood where they found themselves in numerous TV and film projects including It Takes Two, Passport to Paris, New York Minute, and others.
The duo also decided not to appear in the Netflix reboot of Full House.
Jodie Sweetin, who played Stephanie Tanner on the popular sitcom, shared her thoughts on why the siblings didn't return for the reboot.

"... They went off and they’ve been wildly successful fashion designers… They’re like, ‘We’ve moved on, we don’t want to do that anymore,’ and I think it was interesting how, like, hung up on that people were," Jodie shared on the Off the Vine podcast in 2022.
She added: "That, like, somehow, it had to be a bad thing, or it had to be an experience, and it was like, ‘No, dude, they quit doing this when they were young, and they don’t want to do it anymore.’ It’s like, that’s OK."
