MIAMI – Daisy Fuentes' Monday update from Vietnam on Twitter -- "So great to travel around the world with someone you love" -- took a different meaning a day later.
The Cuban-American former MTV VJ, whose family lives in Miami, recorded when her husband, 80s rocker Richard Marx, moved to subdue a man who was pushing the flight attendants and pulling their hair.

"On our flight from Hanoi to Seoul, a guy sitting in the next row from us got crazy and started attacking the flight attendants and passengers," Fuentes wrote on Instagram.
When Fuentes was in danger, she claims her beloved "Right Here Waiting" singer was the first to help subdue the violent passenger. Marx later said he wasn't a "big hero" but "just did what I would hope anyone would do in the same situation."
Korean Airlines reported the man on their flight from Vietnam to South Korea drank two and a half shots of whiskey before the chaos started. Flight attendants used rope to restrain the man, but he managed to free himself three times, according to Fuentes.
Citing Incheon police, the Yonhap News Agency reported that the passenger was a 34-year-old South Korean man who became drunk after drinking hard liquor on the flight.
