November 2023: Harbour and Allen Attend Basketball Game Together Amid Split Rumours
Speculation began to swirl in October 2023 when eagle-eyed fans noticed that Allen had unfollowed Harbour on Instagram. This was further fuelled when amateur sleuths noticed the pair hadn't been pictured together for a while, although this can predominantly be put down to Allen appearing in "The Pillowman" in London's West End throughout the summer with Harbour remaining in the US.
However, the couple put our minds at ease on 1 Nov. when they were pictured at a basketball game in New York watching the Knicks take on the Cleveland Cavaliers. And to confirm their solid relationship status, Allen reposted a shot from a fan who captured them on the big screen at the game.
