The heart-throb tried the Filipino delicacy "balut" during a recent holiday to one of the country’s island volcanos. And to prove he went through with it he asked a pal to videotape him as he peeled the egg and gulped down its contents.
The 24-year-old High School Musical star showed the clip during an appearance on Jimmy Kimmel Live!, boasting that he enjoyed the snack so much he asked for seconds.
"There was a fully-formed little bird in the egg ... It wasn't that bad. I ate, like, three more that day," Zac claimed.
"There was, like, a hard part with, like, the beak and stuff. I didn't want to eat that."
Balut is a duck embryo that is boiled and eaten in the shell. The broth like snack is believed to be an aphrodisiac. So there you go, Zefron fans that's the way to get him in the mood for romance.
