There are two real reasons why Jerry Lee suddenly became thinner. First of all, because Jerry Lee took over a TV series, he had to lose weight because of this role. This makes sense, because actors have to sacrifice a lot for their roles. For example, some actors have cut off their long hair for many years, some actors have long hair for their roles, some for losing weight, some for gaining weight, and so on. According to informed sources, Jerry Lee's TV series will start shooting when he is in his twenties, so it is natural to find a way to be younger.
The second reason is lighting and retouching. In other words, Jerry Lee is not as thin as we look, just because of the lighting engineer's perspective and later retouching, Jerry Lee looks more relaxed and thinner. In the entertainment circle, this is also common, especially for many female stars, the photos that flow out have to be retouched later, which is completely different from the scene map.
Now that Jerry Lee and Fan Bingbing have broken up for a long time, it has been decided that there is no need to tie them together for speculation, which is disrespectful to both of them. In fact, what actors want us to pay attention to is not themselves but their works. After all, this is the embodiment of their value.
