With just hours to go until the VMAs, Justin Bieber has been tweeting about his preparation.
The singer posted two videos to his Instagram and Twitter accounts showing him practising his performance for song 'What Do You Mean?"
He's also seen swaggering through the auditorium during rehearsals pausing beside seats held for John Legend, Chrissy Teigen and Kanye West.
But he pays a little extra attention for the seat marked for Britney Spears (33).
The 'Baby' singer says 'Britney I'm back' before leaning over the poster of her face to deliver her a smacker.
Earlier, Britney supported Justin's comeback, promoting his song 'What Do You Mean?' by holding a sign at Planet Hollywood casino in Las Vegas.
Could this be a sign of a future collaboration?
Tonight's VMAs is one of the music industry's hottest events - with Miley Cyrus all set to do hosting duties.
We CANNOT wait.
