When Lily Allen discovered a tarantula in her bed

Singer Lilly Allen has revealed how she was terrified after discovering a tarantula in her bed during her recent trip to the Amazon rainforest.

The songstress spent a week in the Brazilian state of Acre filming a documentary for the World Wildlife Fund charity in a bid to publicise the need for conservation efforts.

But the British singer admits she wasn't a fan of the area's scary populace.

"I've been there (Brazil) a few times on tour but only to like Rio and Sao Paulo," the Daily Star quoted her as telling Sky news.

"It was really nice to go up to the rainforest - even though there was a tarantula in my bed one evening, which was slightly terrifying. I just screamed and ran out of the room."

A report in The Sun newspaper documents Allen's terror at her confrontation with the critter - she sprinted from the hut, screaming: "There's a f**king tarantula in my room! It's about the size of my hand."
