Selma Blair at The 'Hellboy 2: The Golden Army' premiere at the Mann Village Theater, Los Angeles, California - 28.06.08

The 36-year-old was promoting the new Hellboy sequel with Mexican director Guillermo del Toro, when she was persuaded to try the 'treat'.

She says, "I had worm tacos. It was a mezcal worm, the one you see at the bottom of the tequila bottle. It's Guillermo's favourite thing.

"They are fried and (they) tasted fine with guacamole. And then I thought about it! So gross.

"Guillermo's wife doesn't kiss him for a week after he eats these worms."
