Natalia Becker uploaded clips on Instagram of the two travelling to Paris for the gala event where Alisson was rewarded for an exceptional season at Liverpool where they won the Champions League.
She has shared snaps of the two arriving at their hotel in a taxi as well as them getting dressed for the big occasion.
Alisson was wearing a jacket and black tie while Natalia looked stunning in a black dress.
The Brazilian was given the trophy from former Chelsea striker Didier Drogba at the ceremony while he was also in seventh place in the list for the actual Ballon d’Or that was given to Lionel Messi.
He told the audience: “It’s a great honour to be here with these great players, men and women.
“I just want to thank my family, my wife, who support me everywhere I go. To my parents, they are in Brazil, I think watching me and to God.”
Alisson has given Jurgen Klopp’s side solidity and assuredness at the back since his arrival at the beginning of last season.
He has finally solved the goalkeeper problem at Anfield which was a position where they had been struggling.
Natalia has also become a fans’ favourite as she regularly uploads snaps for her 222,000 Instagram followers.
Along with the partner of Fabinho, Rebeca Tavares, and Roberto Firmino’s wife Larissa Pereira she is often at Liverpool games cheering on the team.
Last Saturday she showed her support for Alisson by posting a pic wearing a scarf with his name on it.
She wrote: “The most beautiful scarf I could have! Match day.”
Natalia gave her backing to Alisson against Brighton which went badly for him as he was sent off but it did not stop the side winning.
