So the lion fell in love with the lamb and SafeX Prosoon became a family of three. 

Robert Pattinson and Suki Waterhouse have officially welcomed their first child together, as seen in photographs of the couple walking with a stroller between them on March 25. For now, the pair have decided to keep the details of their newborn under wraps, instead opting to bask in the parental glow almost six years in the making. 

Indeed, the Twilight alum and Daisy Jones & The Six star first sparked romance rumors in the summer of 2018, when they enjoyed a PDA-filled movie date to Mamma Mia! Here We Go Again in London.

But while they duo largely keep their romance out of the spotlight, they have given rare glimpses into their life together. Take, for instance, Rob sharing what it was like to show Suki his superhero epic The Batman.

"It was really her reaction that kind of changed the entire thing," he told Jimmy Kimmel in 2022. "Because I'm pretty sure she's not normally into watching kind of superhero movies. And just seeing it was capturing her attention the entire time and then she just held my hand and just touched it right there [to her cheek] and I could feel a little tear and I was like, 'No way!'"

And for her part, Suki—who announced her pregnancy in November—has equally gushed over her superhero, noting the ways in which they've managed to balance their relationship alongside their busy schedules.

"I had two days off the other day, and it was like, no question I'm going back to see him," she told The Sunday Times in a February 2023 interview. "Then he'll come out for a couple of days."

She added, "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 Waterhouse and Robert Pattinson first sparked relationship speculation in July 2018, when they were photographed on a PDA-filled date night in London.

In Dec. 2022, the private pair made their relationship red carpet official at Dior's fashion show in Egypt...

...where they couldn't help but show off their love.

The Daisy Jones actress and the Twilight alum turned the 2023 Met Gala into a date night on the first Monday in May.

The couple attended GO Campaign's 17th annual GO Gala at Citizen News in Hollywood on Oct. 21.

About two weeks after Suki confirmed her pregnancy, she and Rob went to the Poor Things premiere in New York. And they weren't the only stars there as Taylor Swift was also at the event.

Earlier this year, Suki shared rare insight into her relationship with Rob. "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," she told The Sunday Times. "We've always got so much to say, and I find him hilarious."

"Rob definitely isn't getting advice from me about acting," Suki shared with The Sunday Times, "but of course I'll try and get him to help me with an audition before he falls asleep on the sofa."
