Sheeran has fun with Crazy Helium Booth

British pop star Ed Sheeran has had a little fun with a crazy new app.

Sheeran revelled in the fun of Crazy Helium Booth on Thursday and posted a video of his `crazy face' to Twitter.

"I finally got the app, bahh," Sheeran squeals in the video.

The caption read: "Finally got helium booth."

The app changes a users face and voice to make them look and sound really funny - a little like an alien with really big eyes.

Sheeran isn't the only Brit to have a fun with helium.

Last month, Dame Helen Mirren sucked on a helium balloon during an appearance on The Tonight Show with Jimmy Fallon.

Like a true professional Mirren preceded to make an acceptance speech while under the influence of the odorless gas, much to the amusement of Fallon.

"I haven't done this since I was about 11," Mirren laughed.
