Robert Pattinson and Suki Waterhouse Expecting First Child

British beloved couple Robert Pattinson and Suki Waterhouse are expecting their first child.

On Sunday, the model, actress, and singer, 31, took the stage at the Corona Capital Festival in Mexico and surprised the crowd by breaking some major news.

In a fan-captured video posted on X, Waterhouse said, "I'm extra sparkly today because I thought it might distract you from something else that's going on."

She proceeded to flap open her coat to reveal a baby bump, as the crowd erupted in cheers.

"I'm not sure if it's working," Waterhouse jokingly added before beginning her music performance.

Waterhouse has been in a relationship with Pattinson for more than five years. They were first romantically linked in July 2018 and began living together in London during the coronavirus pandemic, where he filmed his titular superhero role in "The Batman".

During that time, an insider told PEOPLE that their relationship appeared to be "On the fast track,".

"They are very loved-up," the source said in July 2020. "They haven't been together that long. But everything seems on the fast track. They are always laughing and smiling at each other,".

During his appearance on Jimmy Kimmel Live! in February, Pattinson disclosed that seeing Waterhouse's reaction to "The Batman" had "kind of changed the entire thing" for him.

"I'm pretty sure she's not normally into watching superhero movies," Pattinson said. "And just seeing that it was capturing her attention the entire time, and then she held my hand and touched it [to her face] and I could feel a little tear. And I was like, 'No way!' ".

In an interview with "The Sunday Times" in February 2023, Waterhouse opened up about her long-term relationship with Pattinson.

"I'm shocked that I'm so happy with someone for nearly five years," she said, adding that the couple never goes more than two months without seeing each other. 

"I had two days off the other day, and it was like, no question I'm going back to see him,".

Waterhouse also shared that she still gets "incredibly excited" when Pattinson's name pops up on her phone.

"I think he feels the same about me," she noted. "We've always got so much to say, and I find him hilarious."

In May, the couple attended the Met Gala together for the first time. The "Daisy Jones & The Six" star dazzled in a sheer floral dress, while the Twilight alum looked handsome in a custom blue suit that featured a sweeping pleated skirt.
