Not a big Pussycat Dolls fan myself, but this was probably a scene:

The Pussycat Dolls (PCD to their fans…), in Singapore as part of their current tour, did a meet-and-greet event at Changi Airport on Wednesday, greeting fans and taking pictures with them.

The Civil Aviation Authority of Singapore and Changi Airport apparently host these sorts of events fairly often. Previous celebrity sessions have featured Air Supply, Mötley Crüe, Jay Chou, Backstreet Boys, Bollywood superstars and top golfer Annika Sorenstam.
