According the couple's business manager, Russell Arons, vice-president of marketing at Mattel, said they feel: "it's time to spend some quality time apart but they will remain friends."

Arons denied there was any truth in the rumour the breakup was linked to the Cali Girl Barbie, arriving in stores. To reflect her single status Barbie will wear shorts and a bikini top, metal hoop earrings and have a deeper tan.

Arons hinted the break up may be due to Ken's reluctance to get married despite Barbie getting a new wedding dress every year.
