Katy Perry has gone from strength to strength over the past decade.

With such hits as Teenage Dream, Roar, Firework, Hot N Cold, and plenty more, the American star has more bonafide hits than many other pop stars on the planet.

Now, to celebrate her more than two decades in the music industry, the 40-year-old star is bringing her Lifetimes Tour to the UK.

Katy Perry originally confirmed six arena dates across the UK earlier this month, but she has just added an extra show at London's O2 Arena.

Tickets are out right now, and we've got all the information you need on how to get involved.

Katy Perry tickets are available right now from a number of online ticket retailers.

This includes the likes of Ticketmaster and See Tickets. Both of which are selling both seated and standing tickets are Katy Perry's arena tour shows.

Speaking out about finally returning to play gigs in the UK for the first time in seven years, Katy Perry said: "I’m so incredibly chuffed to bring The Lifetimes Tour to the UK! I can’t wait to have a big sing along of all the songs you love and more! It’s going to be a giant dance party, and everyone’s invited!"

Katy Perry has also vowed to donate £1 from every ticket to UK grassroots music venues.

Considering she's playing London's O2 Arena twice, that's potentially more than £40,000 donated to the cause.

Speaking about this commitment, Katy said: "I’m proud to donate £1 from every ticket on the UK leg of The Lifetimes Tour to Music Venue Trust so that venues like Water Rats and Scala, where I played my first UK shows, can continue to usher in the next generation of music talent."

Mark Davyd, CEO Music Venue Trust, said: "We want to say a huge thank you to Katy and her team for stepping up to support grassroots music venues, artists and promoters. The contribution from these shows will keep venues open, get new and emerging artists out on tour, and enable promoters to bring the best in new music to our communities."
