The celebrity uploaded an image of himself brandishing the budget handset to his personal page on Chinese social network Weibo.
It is unclear whether Lin's iPhone 5C is a completed version of the device, or just its back casing, which has already been glimpsed in a string of leaked images.
Previous rumours have suggested that Apple intends to phase out one of its existing iPhone models with the launch of the lower-cost handset, releasing it alongside the flagship iPhone 5S.
The Cupertino firm is yet to officially announce the budget iPhone, but a recent inspection of one of its factories documented workers handling components for such a device.
Apple has been tipped to announce the iPhone 5C alongside the iPhone 5S in September.
