ITV's Quiz actor Michael Sheen has a secret family link to Michael Jibson, who stars as Tecwen Whitlock in the Who Wants to be a Millionaire? drama.
The series is based on a true story, and follows the infamous scandal of Charles Ingram - who cheated his way to winning £1million.
Sheen, who plays show host Chris Tarrant in the series, has a cousin Caroline who is married to Michael Jibson.
Caroline shared the surprise news on Twitter when she uploaded a snap of herself alongside the two lads, and they all looked super happy.
Michael's cousin donned a huge grin as she posed in between the actors, who were equally as smiley.
Caroline showed her support for both Michaels, who are starring in one of the biggest dramas of the moment.
She wrote alongside the snap: "Stupidly proud of the two Michaels in my family tonight.
"One doing an impression of a Welshman and the other a pretty well known Englishman. #Quiz "
Fans were blown away by the news, but admitted they had noticed the uncanny resemblance.
Others praised their acting, with one writing: "Such a talented family! It was an awesome show".
Another wrote: "It’s a brilliant drama. Really enjoying it. Both Michaels are fab [thumbs up emoji]".
A third penned: "So you should be! Bloody marvellous xx"
The hit mini-series will air its final episode tonight, and actress Sian who plays Diana has hinted "all may not be as it seems".
Encouraging people to have an open mind, the star suggested "new evidence" would be included and that the "truth" will be revealed.
Viewers will have to tune in for the epic finale to see the "new evidence", so they can finally make their minds up over who they believe.
*Quiz concludes tonight at 9pm on ITV
