Resurfaced footage shows Jedward saying they want to "show respect" for The Queen.
The Irish double act caused recent controversy after calling to 'abolish the monarchy' just days after the Her Majesty's death last week.
Now an unearthed video shows the moment the pair appear excited after performing for the monarch in Ireland – causing confusion amongst fans.
Real names John and Edward Grimes, the short clip, which has now gone viral on Twitter, sees the twins in matching suits praising The Queen.
After taking to the stage in front of Queen Elizabeth, they said: "We wanted to make it a party."
"We wanted to show respect for her and give her an awesome performance. We've sang for Barak Obama and now we've sang for The Queen," they added.
The video has already been seen more than 40,000 times and people are questioning the twins who are seemingly no longer fans of the Royal Family.
"For two people that seemingly despise the monarchy, Jedward seemed pretty excited here that they performed for Her Majesty," Tweeted one fan.
"Excited to perform for the monarch as and when it suits," added another. "They are only taking digs at the monarchy cause they got ripped the p**s out of over here whilst on X Factor," said a third.
More users are calling the pair "hypocritical" while others are saying the pair are just involved in "one big publicity stunt".
The pop twins, who rose to fame on X Factor, took to Twitter last Saturday to voice their opinion and asked our new king to "give the people real democracy", after his reign was officially declared.
The 30-year-olds wrote: "Abolish the monarchy and give the people real democracy!"
The duo then shared a second tweet which said: "King Charles should hand back the six Irish counties on his visit to Northern Ireland – No war! Just words! It's time."
While many Twitter users retweeted and 'liked' the comments, others slammed the pair for their opinions.
One person replied: "Guys your embarrassing yourselves now enough enough."
Another said: "Whoever is babysitting these two clowns needs to be reprimanded," while a third added: "This is the time where 'children should be seen and not heard'."
Other people seemed open to the debate, with one person tweeting: "Don’t disagree in an ideological sense but in practice would be hard."
"Money used for coronations and funerals that could go to the poor," replied another.
