EXO's Kai was embarrassed by a sign held up by a foreign fan while attending a fashion show for Gucci in Italy.

The popular star was spotted looking flustered by a sign held up by a fan that referred to a funny moment that Kai was in while filming for an episode of 'Knowing Brothers' and failing hilariously at a game of Whisper Challenge.

Kai was seen looking flustered as he read the sign carefully. 

The first sign reads as follows: "Inside my panties... two syllables?!" while the second sign wishes Kai a happy birthday in Korean. Netizens have been cracking up at Kai's reaction, stating: 

"Kai is so darn cute."

"I like EXO just because of Kai."

"I'm going to go back and watch the segment again just because of this."
