Emma Roberts‘ pregnancy reveal was one she—and her mother—will never forget.

During the Oct. 19 episode of Jimmy Kimmel Live!, the 29-year-old actress looked back at how her mom, Kelly Cunningham, “spilled the beans.” To set the scene, Roberts explained that her mom doesn’t own a computer and that she had a flip phone up until three years ago. So, the American Horror Story star decided to buy her an iPhone for Mother’s Day.

“I was, like, ‘Now we can FaceTime and iMessage. And like, how sweet.’ And it was just such a love fest,” Roberts recalled. “And it was the worst thing I ever did.”

First, Cunningham set up Google Alerts on Roberts. “So, she’s like, ‘Emma, have you seen this photo from 2010?’ I was like, ‘Yes, I’ve seen this photo,'” the Scream Queens alum said. “So, I was getting flooded with ‘Is this true’ and ‘Have you see this and that?’ I was like, ‘This was a bad idea.'”

Then, Cunningham got Instagram. And while Roberts said the proud parent initially had only “a couple hundred” followers, she soon accumulated “a couple thousand” and “had no idea what she was dealing with.”

Soon, Cunningham was interacting with Roberts’ fans. And while the Holidate star was trying to keep her pregnancy “low-key” at the time, Cunningham was thanking followers for their well-wishes on the baby news. For instance, when a commenter asked point-blank if Roberts is pregnant, Cunningham replied, “Yes!!” And when another follower congratulated the family, Cunningham wrote, “Thank you so much! Very excited.”

“It was a disaster,” Roberts said. “And I found it all out on a plane. So, I couldn’t get to her. Like, I couldn’t call her or attack her. I could just iMessage with her and DM her and ask her to please stop.”

Her mom didn’t seem to understand why her comments were a big deal, either. “When I said to her, ‘Mom, you revealed my pregnancy,’ she goes, ‘Emma, you announced it,'” Roberts said. “I said, ‘No, I didn’t. That was a tabloid.’ She’s like, ‘Oh, that wasn’t clear.'”
