The stunning brunette – who married the Leicester City striker in May – donned a red cap, emblazoned with the word England as she cheered on from the stands.
Flashing a beaming smile, Rebekah chatted away happily as she waited for the match to kick off.
Opting for an all-black ensemble, the star glammed up her look with a grey leopard-print bomber jacket and mirrored sunglasses.
In a gorgeous selfie, posted to Instagram on Monday evening, the WAG revealed she was wearing a silver chain with a 'J' trinket.
Could the sweet tribute to her new husband be a lucky charm? Let's hope so.
Last week, during England's game against Wales, Rebekah was snapped cheering away as she watched Jamie score his first goal in Euro 2016.
The football hero's new bride was spotted among the English fans in the stadium in Lens, throwing her hands in the air as they celebrated the strike.

Following the match, Rebekah took to Twitter to show her support.
"And that's what the boy can do... Proud #ENGWAL #11," read the proud tweet.
Earlier in the tournament, Mrs Vardy had criticised the 'threatening' behaviour of police during England's clash with Russia – which was overshadowed by violent scenes during the Group B match in Marseille.
Writing on Twitter she slammed the treatment of fans, claiming she was teargassed by police in her "worst ever experience" at an away game.
She has since explained the comments and admitted she feared for her own safety due to the police's heavy-handed tactics in Marseille.
"The police are meant to be there to protect you. Well, I didn’t feel protected; I felt threatened," she said.
