Shouldn't sick baby Princess Tiáamii be tucked up in bed, Jordan?

But when Jordan's daughter Princess Tiáamii caught the infectious disease while on holiday in Los Angeles, the glamour model was insistent life should carry on as normal.

Despite medical recommendations to keep a chicken pox sufferer at home, the glamour model brought the nine-month-old baby for a day out in Beverly Hills - and her spotty appearance certainly caused a stir.

Katie Price, 29, and husband Peter Andre, 35, flew into Los Angeles with their three children Princess; Harvey, five; and Junior, two; on Friday.

The couple are filming and promoting their reality TV show, which has recently been snapped up by U.S. network E!.

During their three weeks Stateside, Katie says she hopes to take the children to Disneyland and fix her veneers at a cosmetic dental surgery.

Arriving at LAX airport, Katie admitted Princess had caught the virus from older brother Junior.

She said: "She's covered in chicken pox. How typical.

"She'll be alright. Junior's just had them."

On Sunday, the couple left Harvey and Junior with the nanny to show ailing Princess the sights of Beverly Hills.

With their reality TV crew and a horde of paparazzi following their every move, the publicity-loving pair brought ailing Princess for lunch at celebrity hangout The Ivy.

Seated outside on Robertson Boulevard in the warm LA sun, the couple kept the photographers entertained with public displays of affection in between mouthfuls.

After lunch, the pair moved on down the road to trendy boutique Kitson, where Katie spent hundreds of dollars on clothes for her children.

When poor Princess appeared to be growing ever more uncomfortable from her illness, the pair decided to bring her to a clinic in Encino, before being redirected to the Children's Hospital in nearby Hollywood.

The couple were swiftly seen by a specialist, who prescribed Princess with medication.

NHS Direct describes chicken pox as "highly infectious" and recommends sufferers stay at home "until all of the blisters have fully crusted over".

The previous day, the couple shopped up a storm with ailing Princess at The Grove outdoor mall.

After buying several bags worth of clothes from Abercrombie & Fitch - which has topless male models on the door - Katie was keen to expand her already extensive underwear collection with lingerie from Victoria's Secret.

Katie's insistent on bringing Princess with her to the shops while she is suffering from chicken pox is sure to add criticism of her parenting methods.

In February, Katie was forced to defend her parenting after her former nanny Becky Gauld accused her of being a bad mother.

Katie is pursuing legal action against Gauld after she claimed in the News Of The World the couple spend no time together as a family and that they were quizzed by social services after their disabled son Harvey scalded himself with boiling water.
