And now the latest update in the saga sees fans certain they've worked out the 'Boyfriend' singer's cryptic caption in a post about Hailey.

He accompanied the post with a pretty mysterious five-word caption which has clearly sent fans into a spiral.
"They wish baby, they wish," Justin wrote.
Now, any die-hard fans of the Biebs will remember that, back in 2010, he released a song titled 'That Should Be Me' which was the tenth and final track on his first studio album, My World 2.0.

Some of the lyrics on the song, which is now over a decade old, read: "That should be me holdin' your hand / That should be me makin' you laugh / That should be me, this is so sad / That should be me, that should be me."
Poetry.
And people now reckon Justin's caption on his latest IG post is a direct reference to that - especially after all his fans rushed to social media uploading posts using the song in reaction to the pregnancy announcement.
