Ariana Grande is one of the most successful pop artists of the 21st century.

At just 33, she has sold over 90 million records, earned multiple Grammy Awards, broken dozens of Guinness World Records, and successfully transitioned from a Nickelodeon child star to a major box-office and Oscar-nominated film star.

But away from the many highs of her career, she has navigated severe public and personal trauma.

On Tuesday, the singer tearfully bid farewell to showbiz as she completed the final show on her Eternal Sunshine tour at London's O2 Arena.

Fans were quick to capture the moment and soak up the atmosphere of the concert, knowing it's the last they'll see of Ariana for the foreseeable.
