Page Six reports that the pair parted ways a couple of days ago, with David and Victoria Beckham's oldest son returning to London from LA after the break up.
Sources said that Brooklyn and Bad Neighbours 2 actress Chloë had both been in LA for the past few weeks but alarm bells rang when they didn't see much of each other.
And The Sun reports that Brooklyn, 17, ended the relationship because 19-year-old Chloë was getting too serious for him.
"Brooklyn is so young with his whole life ahead of him," a source said.
But even though it looks bad now, it seems there is hope for the former lovebirds.
The source continued: "Like any youngsters in a relationship, there wouldn't be much of a surprise if they get back together.
"Especially if they go on to mix in the same circles."
The power-couple first announced that they were seeing each other back in May when Chloë confirmed that they were in a relationship on Watch What Happens Live in the US.
Let's hope they'll be back to calling each other "bae" in cute Instagram photos very soon!
