On the evening of May 14 (Vietnam time), American pop star Jason Derulo posted a photo of the mask once revealed by Vietnamese singer Son Tung M-TP on his Facebook page on May 8.
The photo is a wooden mask with pink cheeks, no mouth, with mysterious and ghostly colors.
Son Tung M-TP's fan community immediately stirred up with Jason Derulo's move. Although Jason did not include any information, many people speculated that the American male artist would collaborate with the Vietnamese star in his upcoming music product.
Previously, Son Tung had successive posts revealing mysterious characters C - M - W. Fans believe that these are the first letters of each word in Son Tung's new song title. But the appearance of the letter W made fans guess that the upcoming song of the male singer from Thai Binh will have an English name.
Jason Derulo posting a photo exactly like Son Tung further reinforces this reasoning.
However, after only about 1 hour, Jason Derulo removed the post about the mask. His incomprehensible action made the online community worried, whether this was really a "teaser" for the handshake with Son Tung, or just a wrong post. Some fans even thought about the case of Jason Derulo's Facebook account being hacked?
