The 31-year-old 'Firework' hitmaker has shown she is still with her man in the wake of his much talked about public display of affection with Selena Gomez in Las Vegas last week.

Katy has taken to her Twitter account to post a series of tweets highlighting her beau Orlando's work as a UNICEF Goodwill Ambassador.

She tweeted, "Instead of giving energy & eyeballs to dumb conspiracy check out how C[OO]L this is" and added a link to an article written by Orlando for Time magazine.

This was followed straight after with another tweet which read: "Donate $25 dollars by 11pm ET at awloveshorizons.org 2enter2 win 1 of 10 voicemail outgoing messages that I'll leave for lucky winners. (sic)"

Her public support for Orlando, 39, has dampened rumours that his recent PDA with Selena has come between them.

On Thursday (12.05.16) Katy posted a cryptic tweet to her fans after she wrote, "Is that all there is?" along with a link to a Peggy Lee song of the same name.

Orlando, 39, was spotted getting cosy with 23-year-old Selena - the ex-girlfriend of Justin Bieber - at the Light nightclub inside The Mandalay Bay Hotel and Casino following her 'Revival Tour' concert in the city.
