It's no secret that Seventeen's Hoshi is a huge SHINee fan, and it looks like fans of SHINee, or SHINee World, who attended the group's 'SHINee World V' opening show at Seoul's Olympic Stadium spotted him in the crowd!

According to several fan accounts, Hoshi was spotted attending the show on September 2 with some of his group members, proudly waving his light stick and calling out, "Taemin-nim! Taemin hyung!" He also fervently sang along to the songs performed!

Word among Seventeen fans is that Hoshi has been a SHINee World since he was 12 years old. Sounds like he had a great time!
