It’s never been a secret – but some people have only just discovered that Hollywood star Gary Oldman is Big Mo’s real life brother.

The Oscar winner is suddenly on everyone’s radar thanks to his Best Actor gong for The Darkest Hour at the Academy Awards earlier this month – and some fans have been left gobsmacked after making the discovery.

Taking to Twitter following the ceremony, some soap fans shared their excitement and utter disbelief at the family revelation.

One person tweeted, “Finding out Big Mo off Eastenders is Gary Oldman’s sister has absolutely blown my head off this morning hahaha”.

Another said, “I’ll never come to terms with the fact Gary Oldman’s sister is Big Mo from Eastenders #Oscars”.

While another added, “How have I only just found out that Big Mo, of Eastenders fame, is Gary Oldman’s actual sister!?”

One EastEnders fan commented, “If there is a better fact out there than Big Mo being Gary Oldman’s sister I want to hear it”.

CONGRATULATIONS TO ACADEMY AWARD WINNER GARY OLDMAN!!! 👏👏👏 @theacademy @darkesthour ◽◽◽◽◽ #GaryOldman #DarkestHour #WinstonChurchill #BestActor #Oscar #Oscars #Oscars90 #Oscars2018 #TheAcademy #AcademyAwards #Hollywoodlife

Another tweeted, “Wtf since when were Big Mo from Eastenders & Gary Oldman brother & sister?????”

And one simply added, “Errrrrr Gary Oldman is Big Mo off Eastenders brother????? Mind blown.”

The shock revelation may be easy to forgive considering the EastEnders actress uses her stage name, Laila Morse – her real name is Maureen Oldman.

While Gary is a huge star in Hollywood, Laila is a soap favourite, with fans excitedly awaiting her return to Albert Square on Friday March 16.

Gary once insisted that his sister is far more famous than him thanks to her role in the British soap.

Back in 2011, Gary revealed that fame “comes in waves”, saying, “Overall I enjoy a certain anonymity. I live a very normal, very ordinary life.”

Somehow, we don’t think Gary’s life will be very “normal” after the success he’s enjoyed so far this year.
