The 27-year-old star has to be in London for The X Factor live shows on Saturday and Sunday nights but took a short trip to the US in between shows.
Cole was reportedly spotted hiding from photographers in the US dancer's car outside an apartment block in Century City, Los Angeles.
She was then all smiles at LAX as she prepared to fly back to the UK ready for the next round of X Factor programmes.
Cole currently has all four of her acts - Katie Waissel, Cher Lloyd, Rebecca Ferguson and Treyc Cohen - still in the show.
