|Kelly Rowland beams for the cameras as she arrives at Los Angeles international airport to catch a flight back to London to resume her X Factor duties|
Wearing a green velour tracksuit, Rowland clutched a drink in her hand and stuck close to her friend as they left an appointment in Beverly Hills.
She kept her face covered with the hood from her jacket, a scarf round her head and large dark sunglasses, but she managed a faint smile for the cameras as she headed to her car.
Her friend carried a plastic bag from organic restaurant Greenleaf, which was probably fully of delicious and healthy things to help Kelly make a speedy recovery.
On Sunday it was reported that Cowell has given the former Destiny's Child singer a 48-hour ultimatum to confirm whether she will return to X Factor and keep her place on the judging panel.
The singer insisted that she wanted to retain her position on the show, but had to consult her doctor to see if she was well enough to fly, as she was been grounded in the US due to a severe throat infection.
A show insider told The People: 'Kelly has been told it’s time to make her mind up. Everyone is supportive of the fact she is ill but other bosses are annoyed at the situation.'
'She doesn’t want to quit. She is adamant that she isn’t worried about the row she had with Tulisa and wants to return but she has to give the ¬producers her word – and fast.'
Kelly has said that rows with fellow judge Tulisa Contostavlos are making her life 'a living hell' and is upset about the way Tulisa is ¬portraying her in the press and the way she’s creating an awful atmosphere backstage.
When she pulled out of last weekend's show, a statement from her people read: 'Kelly is devastated she won't be here for this weekend's show. She is extremely ill with a viral throat infection and her doctors aren't permitting her to fly.'
And Kelly told the Sun she was suffering from an 'extremely rare' illness, and has been in tears about her situation all week.
