Two viewers were in for a shock during tonight's Saturday Night Takeaway when they played a Mother's Day theme game.
The mums took part in the quiz Mam, Would I Lie To You? during which they had to work out untruths.
And they found out one thing that definitely wasn't a lie - they're going to be grandparents.
Their daughters broke the news in unison assisted by hosts Ant McPartlin and Declan Donnelly, and viewers couldn't help but notice their mums' 'polar opposite' reactions.
While one mum smiled and clapped, an amused Dec pointed out that the other grandma-to-be looked 'furious' at the news.
"I think Brenda's pleased. She looks furious," he wondered.
"Polar opposite reactions from two women finding out they’re going to be grandparents," said a viewer on Twitter about the moment.
"That woman looking raging when she was told she was going to be a grandma," tweeted another.
"But absolutely buzzing for the 5* Holiday to Malta."
"Think that mam was more excited about the holiday to Malta than becoming a grandma," tweeted another.
Another wrote: "The woman’s face when she found out she’s gonna be a grandma. She looked fuming."
Brenda was branded an 'icon' on Twitter for her reaction.
Another viewer said: "I'M SCREAMING. That grandma's face omfg."
And another suggested that she might not have heard 'properly.'
"I don't think Brenda heard properly about being a grandma. I think she thought it was the other mum," they suggested.
Other viewers were moved by the moment ahead of Mothering Sunday.
"Aw finding out ur gonna be a Grandma on #SaturdayNightTakeaway," said one.
"Congratulations on those lovely ladies on becoming a grandma," tweeted another.
And Saturday Night Takeaway tweeted: "An early Mother's Day treat for Pat and Brenda, awww! Congrats ladies!"
