The 17-year-old aspiring photographer and the 19-year-old actress only confirmed their relationship in May, but decided to end it sometime over the last few weeks when Brooklyn was in Los Angeles with his family, according to the New York Post newspaper.
The Beckhams, including dad David and mother Victoria, arrived back in London on Tuesday (30.08.16) following a two-month break in Los Angeles and Brooklyn was said to have looked downbeat upon his return.
Brooklyn and Chloe had spent a large chunk of the summer together, attending various public events and documenting their relationship via social media.
It is, however, the second time they have split after they briefly dated back in 2014, before reuniting earlier this year.
Chloe revealed they had got back together in May 2016, saying she wanted to be open about their relationship rather than trying to keep it a secret.
She said previously: "We're in a relationship. It's fine. It's no biggie.
"And I think that, you know, the more I don't make it mysterious, the more that people don't care. So yes, we're in a relationship."
The 'If I Stay' actress also revealed Brooklyn was a major source of encouragement and strength for her.
She shared: "My boyfriend is a huge support.
"I mean, don't get me wrong, I don't need a man for anything.
"But when I'm feeling bad about myself, he's like, 'Stop. Look at what you say in interviews. Look at what you stand for.
"Listen to your own words, because you're as beautiful as you say you are!'"
What's more, Chloe has previously gushed about the Beckham family.
She said: "[The Beckhams] are a great family. They don't tout their money either.
"They'd [the family] understand the travel, the sex scenes with random people, the crazy schedule."
