Following the 2-1 result, the 47-year-old shared a capture of Gareth Southgate, also 47, and Harry Maguire.
In the snap, the footballer could be seen squatting on the floor, while the England manager consoled him.
The former professional footballer wrapped his arms around Harry, 25, and leant his head in close to him.
In the heartfelt post, the Britain’s Got Talent judge told her followers not to dwell on the result, but instead celebrate the squad’s achievements at the World Cup 2018.
Beside the snap, Amanda penned: “Let’s not #blame or #hate let’s #celebrate how far we came and how #united we were #tonight #godbless @england.”
Fans rushed to comment on the post, with one writing: “So proud of our team.”
Another Twitter user penned: “They did awesome to get so far.”
“I am so gutted for the boys but look how far they got us, they give it the best,”(sic) gushed a third.
A fourth person told the star: “No one to blame, just plenty to be proud of. What a great team!”
Ahead of the game, Amanda and her two children, six-year-old Hollie and 12-year-old Lexi, were spotted getting into the spirit of the game on Instagram.
In the capture, the trio had donned red crosses on their cheeks in support of the England team.
The mother-of-two and her eldest daughter could be seen grinning at one another, while Hollie put her thumbs up as she beamed at the camera.
The star, who married her second husband Chris Hughes back in 2008, captioned the snap: “Ready for the #big #match @england #threelionesses on a #shirt #itscominghome.”
It came just days after Amanda had insisted that Gareth Southgate should be knighted for his role in the World Cup 2018.
Clearly overjoyed about England’s win in their game against Sweden during the quarter-finals, the star gushed over the result.
“Busy #celebrating last night! I knew the @england would do it,” she penned.
Amanda went on to praise the retired professional footballer for maintaining his composure during the match.
“This man Gareth Southgate deserves a knighthood #strong #dignified the #calm in a #storm #itscominghome,” the star concluded.
