Apparently, age is more than just a number to model Suki Waterhouse. According to a print report from Star Magazine, the 22-year-old runway star is planning to dump her award-winning actor beau, Bradley Cooper.

"Suki is keeping her distance," a source revealed to the tabloid, adding claims that Waterhouse is breaking up her one-year romance with Cooper because she feels "too young" to be getting serious with the 39-year-old "American Hustle" star. "Bradley wants to settle down and start a family," said the insider, when commenting on one of Waterhouse's reasons for ending their romance.

While the couple isn't officially on the outs just yet, the magazine claims that the U.K. native will soon make the split permanent. "She thought it was better to end things now rather than letting them drag on," said an insider.

The breakup rumors come shortly after reports surfaced that the couple were planning to tie the knot. Not only did Cooper reportedly call his model girlfriend "the one" during his appearance at the 2014 BAFTA awards in February, CelebDirtyLaundry also speculated that the couple was prepping for an engagement earlier this year.

"Despite their age difference and the long-distance relationship, Bradley and Suki are getting serious," reads the gossip report, which reported that the 2014 Oscar nominee would soon be "popping the question."

The couple first began dating after meeting at the 2013 Elle Style Awards. Following rumors of their flourishing courtship and the publication of multiple side-by-side candids, Waterhouse confirmed their relationship status to Elle UK last December, referring to Cooper as her boyfriend and classifying their romance as "boring."

“I don’t talk about my boyfriend because it’s boring. At least, that’s what I decided to tell you when you asked," Waterhouse told the magazine, later adding, "The truth is, if I start talking about him, I probably won’t be able to stop. And I don’t really want to talk about him, you know?”

The duo were last seen together sitting front row at the 86th annual Academy Awards in Los Angeles on March 2.
