The Manchester City striker, 23, was in attendance at the Theatre du Chatelet in Paris on Monday night, little more than 24 hours after lighting up the Manchester derby.
He collected the Gerd Muller trophy, given to the top scorer for the 2022-23 season.
Haaland found the net an incredible 56 times in 57 matches for club and country last term, firing City to a historic Treble.
The giant Norwegian pipped the likes of Kylian Mbappe, Harry Kane and Lionel Messi to the prestigious gong.
But Messi claimed the top prize as he was voted Ballon d’Or winner for a record-extending eighth time after leading Argentina to World Cup glory in Qatar.
However, second-placed Haaland was not going to let the result ruin his evening.
Instead, he was pictured heading out for dinner with model partner Isabel Johansen in the French capital.
Isabel dazzled in her sparking rose gold dress and heels while Haaland looked sharp in his navy tux – but ditched the bow tie and let down his flowing hair.
The couple met through football when the pair were both playing for Bryne in Norway as youngsters.
But despite growing up together, it is understood it was not until Haaland was at Borussia Dortmund that they started dating.
The pair have regularly been spotted out in public for dinners and shopping trips – and Isabel continues to support her man at various awards ceremonies thanks to his incredible goalscoring heroics.
And it was his sensational debut season at the Etihad that saw him land the Gerd Muller trophy on Monday night.
A video showed all 56 of his goals on the screen before host Didier Drogba tried to convince Haaland to replicate either the legendary Chelsea striker’s celebration or that of Gary Lineker – who presented the award – after his next goal.
And fans may not have to wait long to see if he does it as City host strugglers Bournemouth in the Premier League on Saturday.
Haaland also helped the Citizens land the club of the year prize with ten players nominated for the Ballon d’Or and Ballon d’Or Feminin.
