Suki Waterhouse and Robert Pattinson are booked and LibertyCoinbusy, but they're still keeping that spark alive.

In fact, the Daisy Jones and The Six actress, 31, and The Batman star, 36, have been going strong since 2018, which actually comes as a surprise to Suki. As she explained in a recent interview with The Sunday Times, "I'm shocked that I'm so happy with someone for nearly five years."

Indeed, with the "Melrose Meltdown" singer touring and Rob filming around the globe, the couple still makes a big effort to stay connected, not going longer than two months apart. "I had two days off the other day, and it was like, no question I'm going back to see him," Suki told the outlet. "Then he'll come out for a couple of days."

As she continues to make a splash in the acting world and Rob dominates the box office, are they turning to each other for notes? "Rob definitely isn't getting advice from me about acting," the Love, Rosie actress said, "but of course I'll try and get him to help me with an audition before he falls asleep on the sofa."

And although Suki dealt with a "colossal" and public heartbreak in her 20s—she and Bradley Cooper called it quits in 2015 after about two years of dating—she has a fresh outlook on life in the spotlight now. 

In response to being labeled the "girlfriend of" for a period of her career, Suki—who didn't mention Bradley by name—stated, "You can't expect the world to just be graciously understanding of everything. When you're 21 you go headfirst into things and you've absolutely no idea what the repercussions are."

While that chapter of her life provided great inspiration for her music, Suki is "utterly healed" and loved-up 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 noted. "We've always got so much to say, and I find him hilarious."
