Not in the mood: Katy Perry may have been feeling the effects of jet lag as she arrived at London Heathrow yesterdayWith her stunning figure, a successful music career and a comedian fiance, Katy Perry is one of the most photographed women on the planet.
But as she touched down in London yesterday after a long-haul flight from Los Angeles, the 25-year-old was far from her usually paparazzi-friendly self.
As she rushed through Heathrow Airport, the California Gurls star attempted to cover her face with a grey scarf after stepping off the 10 hour flight.
Although used to jetting back and forward across the Atlantic, perhaps the singer was feeling a touch of jetlag this time and was looking forward to crashing out on her hotel bed.
But before she could sleep it off, she had to rehearse for her X Factor live performance on Sunday night
Writing on her Twitter page, she said: 'JUST finished rehearsals for SUNDAYS X Factor! I'm so excited to do this song in this way! It's going to be brighter than the moon!'
It will be her second appearance on the show this year after she stepped in to replace Dannii Minogue as a judge when the Australian was on maternity leave earlier this year.
I want to be alone: Katy still kept herself hidden as she sat in the chauffeur-driven car to her hotelHer flight to London came as she unveiled a new photoshoot to promote the launch of her new fragrance, Purr.
The pop star is pictured crawling around in a latex catsuit, complete with a tail and ears, alongside a huge ball of hot pink yarn for the ad, which was shot by photographer Miles Aldridge.
The shoot was inspired by the cat-shaped fragrance bottle, which features bejewelled eyes and purple colouring.
It is the singer's first fragrance and it is set to be released in November.

Close friends of the couple, including Rihanna, Jonathan Ross, Noel Gallagher and David Walliams, are expected to make their way to India for the wedding ceremony on Saturday October 23.
'We love each other and we want to get married in front of our friends and family and keep it very normal,' 35-year-old Brand told fans on Tuesday.

Folk dancers are expected to welcome the couple with a traditional dance and fireworks.
From here, Brand and Perry will travel in a horse driven cart to the main garden where a Hindu ceremony will be conducted in front of a small fire.
It was in the same gardens that Brand proposed to Perry earlier this year, when they spent 10 days exploring India during a romantic Christmas break.
Brand planned every minute detail for his special moment, even down to what his future wife would wear a £600 traditional Indian dress.
The pair began their engagement night by watching fireworks while sitting on an elephant and were then taken to the Mughal Garden on horseback.

The presidential suite at the palace is likely to set the couple back a whopping £8,500 per night, while celebrity guests can expect to pay at least £600 a night for a deluxe room.
