Charlene, who is also known by her nickname Ah Sa, modelled gym and yoga gear from Adidas' spring/summer collection. The star posed in various yoga shapes and showed how flexible she is by doing the splits.

However, Charlene has only recently become the new face of Adidas by chance. Charlene's Twins bandmate, Gillian Chung, was unveiled as the sports brand's first ever Hong Kong spokesmodel only last October picked because she was seen as the more sporty of the duo, having been in her school's athletics team.

Gillian, who has the nickname Ah Gil, was axed after being implicated in the Edison Chen sex photos scandal several weeks ago, when photos of Edison and women purportedly including Gillian having sex leaked onto the internet.
