The X Factor judge looked healthy and radiant as she visited a coffee shop near her home in Surrey.

She arrived at the Starbucks off the A3 near Guildford in a chauffeur-driven car.

The 27-year-old singer was dressed casually in a white top, loose-fitting blue jeans and flip flops.

She seemed upbeat as she smiled for photographers, chatted and posed for pictures with fans.

According to onlookers, she spent a few minutes inside the shop where she spoke to the manager and staff.

The Girls Aloud star was diagnosed with malaria days after collapsing during a photoshoot on July 3.

She contracted the disease while on holiday in Tanzania with her friend Derek Hough in June.

After spending a prolonged period in hospital she has been recuperating at her £6m home in Surrey.

She is apparently keen to get back to work after missing the final auditions of the X Factor auditions and the boot camp stage.

She was replaced by Pussycat Doll Nicole Scherzinger.

Simon Cowell's brother, Tony, told Sky News the singer was due to return to the show for the next round held at the judges' houses.

Last year she travelled to Marrakech, Morocco, to select her final three contestants, but this time she will stay in London.
