Adele paused one of her Las Vegas shows to question her audience about the tragic implosion of the Titan submersible.
The OceanGate 'Titan' submersible that billionaire tourists used to explore the wreck of the Titanic suffered a "catastrophic implosion" killing all those onboard.
French and British authorities assisted the US and Canadian Coast Guard in a search and rescue mission for four days after the OceanGate Expeditions submersible went missing on June 18.
Many experts said the submersible wouldn't have passed strict safety protocols in the US and Canada.
On Friday, after news of the implosion was published, Easy On Me singer Adele briefly paused her Vegas residency to discuss the submarine.
She said the incident was "so sad and so tragic" and added that she and her friends have been debating whether they would have gone on the trip to the Titanic wreckage.
Adele said: "Everyone’s like, 'I would never do that.' But that’s a lie, cause a lot of people would do that.
"I want to do a vote, not in mind of what happened, cause that was so sad and so tragic, but before this week, how many people would, if they could, would go down to the very, very bottom of the ocean to see the Titanic? Raise your hands."
She went on to say she "wouldn't do it either" as she's a "bit of a p***y."
"I’m a scaredy cat of everything," the star said. "I wouldn’t even go on roller coasters. But also, I just genuinely don’t have an interest in the deep sea or space, so that’s why."
Billionaire adventurer Harding, 58, Pakistani-British businessman Shahzada Dawood, 48, his son Suleman Dawood, 19, French underwater explorer Paul-Henri Nargeolet, 77, and OceanGate founder Stockton Rush, 61, were all on board the submersible.
A “catastrophic failure” was said to have taken place, imploding their sub and killing everyone on board instantly.
Due to the vast pressure that deep in the sea, the wreckage sits around 3,800 metres below sea level, the pressure is about 375 atmospheres.
The men would have felt nothing as they were subjected to the equivalent of 5,500 pounds of force.
