The English actress and musician pointed down to her belly and all but confirmed the big news while performing on stage.
Suki was performing as part of her ongoing live tour on Sunday at the Corona Festival in Mexico City.
Looking dazzling in a sparkling lilac dress, sparkling white boots, and a fluffy baby pink jacket, she addressed the excited crowd.
She said: “I thought I’d wear something sparkly to distract you from something else I’ve got going on…
“I’m not sure it’s working,” Suki joked before singing [as seen above].
At that point, she made a gesture to her stomach, resulting in an eruption of cheers from the audience.
The couple has not confirmed they are expecting beyond this statement from Suki, but it would be their first child.
‘SO HAPPY FOR THEM!’
Fans went wild over the sweet news, as one wrote on X (formerly Twitter): “So happy for them!”
“That earthquake? Oh it was just everyone falling to their knees,” joked another.
A third added: “That baby just won the gene lottery.”
‘SHE’S SO HAPPY AND EXCITED’
Before the announcement, a source told ET that the A-list pair were expecting their first child.
“Suki Waterhouse and Rob Pattinson are expecting their first child together. She is so happy, excited, and appreciative of this experience. Suki and Rob are adorable together,” the source said.
The news comes after Waterhouse first showed what appeared to be a hint of a burgeoning bump while performing in a midriff-baring top at Austin City Limits Music Festival on Oct. 15.
One week later, she posed with the actor in a sheer, empire-waist gown on the red carpet at the GO Campaign Annual GO Gala in Los Angeles, California [seen below].
The 2023 Met Gala saw Suki and Robert making another rare red carpet appearance together.
SUKI AND ROBERT
Robert, 37, and Alice Suki Waterhouse first sparked romance rumors after they were spotted kissing on a London date night in July 2018.
They got together after he spit from FKA Twigs in 2017.
The Twilight actor and Daisy Jones & The Six actress have been going strong for five years but have kept a low profile.
In February 2023, the couple took another big step by purchasing a California home together, according to Dirt.
The duo reportedly bought the Hollywood Hills home for $5.3 million.
In October 2023, rumors also spread when a TikTok user claimed that the actress had begun following baby and pregnancy Instagram accounts.
The pair has made it clear in past interviews that they value privacy.
“If you let people in, it devalues what love is,” Robert told The Sunday Times in 2019.
“If a stranger on the street asked you about your relationship, you’d think it extremely rude. If you put up a wall it ends up better.”
Four years later, Suki told the same outlet about the movie star: “I’m shocked that I’m so happy with someone for nearly five years.”
She continued at the time: “I had two days off the other day, and it was like, no question I’m going back to see him.
“Then he’ll come out for a couple of days. I’m always incredibly excited when I see his name pop up [on my phone] or even a text, and I think he feels the same about me. We’ve always got so much to say, and I find him hilarious.”
Suki has also dated numerous high-profile celebrities.
She previously dated actor Bradley Cooper – who was 17 years her senior – for two years from March 2013 to March 2015.
Suki also had a two-year relationship with Narcos: Mexico star Diego Luna.
This would be the first child for either the Batman star or singer/actress/model.
