They wowed both Simon Cowell and Cheryl Tweedy at this year's Judges' Houses stage of The X Factor, but it turns out The Cutkelvins have some serious music history in their family as they are related to a member of The Beatles.
It seems talent runs in their family as siblings Kay, Jay and Sheeran are related to the one and only John Lennon!
The group are related to The Beatles legend through their grandma, Barbra Lennon.
A source told a national newspaper, "The Cutkelvins have had musical success thanks to Shereen's career with girlband Neon Jungle but have always kept their family link to Lennon quiet.
"Sadly, they're too young to have met him but it's a nice thing to be able to say you're a descendant of one of The Beatles. Their gran Barbra was John's second cousin."
The Cutkelvins sailed through to this weekend's second live show when they performed their own rendition of P!nk's 'What About Us' last Sunday night.
Despite their mentor Simon Cowell being absent from the show after falling down the stairs and injuring himself, the music mogul is expected to return this weekend for Viva Latino week.
At the time of publication, ITV bosses are yet to announce which songs the 14 remaining acts will be singing to win over the public.
Last week, after just one song, Talia Dean from the overs and Spencer Sutherland from the boys' category were evicted from the show after they received the least votes on Saturday and Sunday.
In other X Factor news, Grace Davies and Rak-Su impressed with their original songs, gaining the highest vote on each night.
Who will impress this week?
It has also been revealed that Rita Ora will be performing on the show, as well as Britain's Got Talent winner Tokio Myers.
The X Factor continues Saturday and Sunday on ITV.
