The 'Promise This' singer - who has stepped out of the limelight ever since she was sensationally axed from the US 'x factor' in May - arrived at the city's LAX airport late last night (07.07.11) clutching Kimberley's hand.
While it had been speculated the pair were in the US on business, a spokesperson for the 28-year-old star suggested their trip will be of a relaxing nature.
Cheryl's representative told MailOnline: "Cheryl is taking some time out as she said on her website last month."
Following her firing from Simon Cowell's TV talent show, the brunette beauty vowed to take time off to "chill" with her loved ones.
She said: "I have had the weirdest past few weeks (nothing unusual there though.) I wouldn't even know how to begin to tell you all about it.
"I have had the time that I have not had in so long to just chill with my loved ones and do the normal things that I like to do. See my friends and family and be with my doggys. It feels long overdue and sooooo good, even my feet are happy to not have to wear a pair of high heels hehe."
