Dressage rider Gemma, 19, came runner up on the most recent series of the ITV reality show alongside boyfriend Luca Bish, 23.
The advert shows Michael slightly rearranging his two Golden Boot Awards, before going to answer a ring at the door.
As he opens the door, an Amazon delivery woman, who just pulled up in a van, says: “I’ve got a package for the boss, the big deal of the house.”
Of course, the former England striker goes to grab the two Amazon parcels, thanking the women.
However, Gemma interrupts and says “Is that for me?”, taking the parcels from the delivery driver.
As Michael looks in confusion, the delivery driver says: “Well she is a big deal.”
The advertisement is promoting “two days of epic deals” from Amazon Prime members.
An added clip shows Michael candidly speaking to the delivery driver on set, he says: “I mean I’ve been in the industry for 25 years, she’s only been in it two months. I mean, I’m clearly the big deal.”
Gemma shared the short advertisement to her Instagram, telling her 2.1 million followers: “Our acting skills definitely aren’t a big deal.”
Michael also shared the video, admitting to his 459K followers: “I guess I’m no longer the big deal of the house?”
Football coach Dietmar Hamann, cricketer Eoin Morgan, footballer Tom Crawford and former footballers Steve McManaman and Shay Given were among those sports personalities to comment.
Amazon UK also commented on the social media post, making reference to a football award Michael had won.
They wrote: “You will always be a big deal to us, Michael. #ballondor”.
Ballon d’Or is an annual football award, judged by a panel of sports journalists.
Michael won the award for the best footballer in Europe in 2001, whilst playing for Liverpool.
The former striker also won two Golden Boot Awards, which are spotted at the start of the advert.
The first he won in the 1997-1998 season, and the second in the 1998-1999 season - both whilst playing for Liverpool.
Michael played for Liverpool between 1996 and 2004, before spending a season with Spanish team Real Madrid.
He later returned to England, where he played for Newcastle United between 2005 and 2009, Manchester United between 2009 and 2012, and Stoke City between 2012 and 2013.
