British pop star Lily Allen is showing off her gutsy side on a trip to South Africa by cuddling up to a cheetah and attempting to ride a zebra while wearing high-heeled shoes.

The Smile hitmaker is in the country this week (ends19Jan14) to shoot a promo for her upcoming single Air Balloon, and she shared details of her daring escapades with fans on Twitter.com.

Allen posted a photograph of her stroking a cheetah - the fastest land animal on the planet - alongside the message, "This happened #notscared."

She followed up with another image showing her looking nervous as she balances precariously on a zebra's back while wearing sparkly high-heeled sandals and denim shorts.

Allen is currently making a comeback after going on hiatus in 2010 to start a family.
