Newly single Katy Perry takes a selfie with Adele while on tour in London

She split with on-again, off-again boyfriend John Mayer in February this year and recently ended things with beau of one month Thomas Pentz, aka Diplo.

So it's understandable that Katy Perry might be off celebrity men for a while - and rather like Taylor Swift - taking some time out to focus her attention on the women in her life instead.

The 29-year-old shared a selfie with superstar Adele on her Instagram on Wednesday with the caption '...And on the 2nd LDN show the Queen graced me with her presence.'

In the slightly monochromatic selfie, Katy had her dark locks slicked back in a high ponytail and wore dramatic false eyelashes with lashings of eyeliner and mascara.

Adele also opted for thick black eyeliner but kept her strawberry blonde shoulder length hair straight and loose. She donned a black hat for theatrical effect.

Three weeks ago Perry shared an affectionate pic with friend DJ Mia Moretti and before that it looked like she was getting cozy with fellow songstress Ellie Goulding, sharing more than one snap of the pair.

And not to forget the California Gurls star rekindled her friendship with former BFF Rihanna. The girls were pictured out at a friend's birthday at 1Oak in New York last month.
Nevertheless the pop diva has a crazy schedule and is currently on her Prismatic World Tour. Adele joined her on her second night at the O2 venue in London.

Perry showcases a variety of astoundingly colourful outfits for her stage show which is touring the world until December - she will perform her final show in New Zealand at that time.
Meanwhile, the brunette beauty graces the cover of Cosmopolitan for it's July issue and opens up about ex-boyfriend John Mayer.
She said: 'I know it sounds really hippie-sh*t, but I’m living in the now and not fantasizing about the future or [being] torn up about the past. I’m super Eckhart Tolle.

'I have a lot of respect for [John] still, and I know it goes both ways. There’s no bad blood, but I’m sure there will be inspired songs.'
This month it was reported that the Firework singer had split with her beau of just over a month, Diplo.

In Touch Weekly reported that the 35-year-old American DJ - real name Thomas Pentz - called time on their romance when it became clear that they 'wanted different things'.

'Diplo broke up with her because she does not want to be in a serious relationship,' a friend of Katy's tells the publication. 'She's doing OK and not too sad about it. They wanted different things.'

According to the pal, the 29-year-old 'freaked out' when Pentz wanted to introduce her
to his parents.

'She doesn't want to get married again - at least not anytime soon,' the friend adds. 'She wants to date and he wanted something much more serious. It was too much, too soon.'

While another source close to the songstress insists Katy was 'really into him', they cite the demands of their careers as a factor in their split, saying Diplo thought the situation wasn't 'fair'

Day-glo: Perry's world tour is bound to be impressive, it continues until December 2014 where it will end in New Zealand
