She's also been sending fans into a frenzy on Instagram with glamorous bikini photos from her travels.

The stunning mum captioned one shot as she posed on a little boat: "9/10 experts say pre-saving LIFETIMES can cure motion sickness."

Fans were blown away as she teased the track, with one writing: "The 30 seconds of lifetimes we heard already touched our heart in such a special way, we are so Ready."

Another said: "This is gonna smash so hard and we cannot wait mother!"

After heading to a load of sun-soaked locations including St Tropez and Paris, Katy hit London to promote the song.

She spoke to The Sun, and told us: "I always wanted to make a dance pop record.

"One third is more dance than I have ever done before. One third is quintessential pop and then one third is rhythmic."

The song is inspired by Katy’s daughter Daisy, three, and the singer’s face bursts into a grin as she talks about her.

She continues: “It is funny how sometimes you’re looking for your soulmate in a partner. It could be a dog, your mum, your best friend, your cat . . . but for me it came in the form of Daisy.

“I wrote Lifetimes about her. Every night, before we go to sleep, I say, ‘I love you’, and then I ask, ‘Will you find me in every lifetime?’ and she says, ‘Yes’.”
