The title looked destined for Watford, who prior to kick-off held a one-point lead at the top of the table, as they went into stoppage time 1-0 up at Vicarage Road against Sheffield Wednesday.
But, just as the Owls had pooped Bournemouth's promotion party last month with a late equalising goal, they did so again - but on a much grander scale.
Atdhe Nuhiu's shot looped agonisingly over Heurelho Gomes to cancel out Matej Vydra's opening goal for Watford and it finished 1-1.
Bournemouth were already two goals ahead at Charlton by the time Vydra scored, with Matt Ritchie and Harry Arter getting the Cherries off to a flying start in London
As news of Nuhiu's equaliser began to filter through, Ritchie scored his second goal of the game and Eddie Howe's men ended the season in style - as champions - with a 3-0 victory
