Their public appearances together have fuelled speculation that Cheryl Cole and dancer Derek Hough are more than just close friends.
And the flames were fanned on Thursday when Derek wrote a public message of congratulations to the singer via Twitter, after her new single Promise This reached number one in the charts.
"Dimples is number one wahooooooooooooooooo !!!! So proud of her, especially after such a tough year," wrote the 25-year-old.
The message coincided with Cheryl's 24-hour flying visit to LA to see Derek and the star certainly looked happy as she walked through the airport following their reunion.
