As ever, Katy showed off her quirky style. Channeling her inner biker chick, the 'Dark Horse' singer donned a leather jacket and boots with a tartan mini skirt, adding a splash of colour to her ensemble with bright red lippie and, of course, her new green do.
Ellie, on the other hand, chose to flash the flesh, baring her washboard stomach and enviable pins. The pretty blonde teamed an Aztec skirt with a black crop top and heels. Joining her pal in the leather stakes, the 27-year-old completed her outfit with a cropped biker jacket.
Despite Katy's grueling tour schedule and Ellie jetting off overseas, the busy pair found time to catch up over dinner at Mayfair's 34 restaurant.
Katy is currently performing the UK leg of her 'Prismatic World Tour'. Having kicked off in Belfast earlier this Month (7 May), the star heads to Glasgow this weekend, before finishing up in London's O2 at the end of May.
Meanwhile, jet-setter Ellie has been spotted on hols in Miami, taking some time out before this summer's festival season.
Although snapped getting cosy in the sea with fitnesss trainer Sam Karl, Ellie has since fuelled rumours she is still with alleged boyfriend Dougie Poynter. Sharing a cryptic Instagram earlier this week, the 'Beating Heart' singer posted a snap of the McBusted stage - does this mean love is still on the cards?
