Adele is being slammed over her 30th birthday party theme

In celebration of her 30th birthday, Adele threw a party themed around one of her favourite movies: Titanic.

But the Oscar-winning pop superstar has come under major fire for throwing a party based on a real-life tragedy, with fans calling it "bad taste".

The mother-of-one shared photos from the lavish party on Instagram last week, in which she can be seen dressed up as Kate Winslet's character, Rose.

In other pictures, guests - including Alan Carr, Zane Lowe, Mark Ronson, and Breaking Bad star Aaron Paul - can be seen dancing while wearing life jackets.

And fans were not impressed.

Posting to social media, followers struggled to see the funny of throwing a party based on a massive tragedy where many people died.

A total of 1,503 people died when the Titanic sunk on its maiden voyage in 1912.

“Is anyone else disturbed that #Adele had a #Titanic themed bday party where they wore life jackets on the dance floor? Like maybe partying whilst mimicking the absolute horror of a ship sinking in the Atlantic isn't cool?” one person tweeted.

"*clears throat* PEOPLE DIED," another added.

A third wrote: "Saving the 9/11 party for the big 4–0?"

While another said: "Isn’t this very inappropriate? Adele’s Titanic themed birthday party had them dancing in life jackets... Thousands of people actually died.”

However, others thought the party was awesome and a fitting tribute to the James Cameron movie.
