Rihanna's not afraid to walk -- or swim -- on the wild side. The "Pour It Up" singer put on a Chanel bikini to go shark diving with pals in South Africa on Tuesday, Oct. 15 -- and naturally couldn't resist sharing a few snapshots from their excursion.
"Shark diving? Yes please!" she captioned one shot, which shows the singer shot from the bottom up, her chest (clad in a pastel pink-and-yellow bikini top) taking up the majority of the frame. The 25-year-old singer finished off the look with a pair of pink-framed cat-eye sunglasses.
In another snapshot, the singer showed herself with two other friends, lounging on the deck of a ship in wet suits. She captioned the photo "Sea Sick," with dollar signs in place of the S's.
One day earlier, Rihanna got up close and personal with nature, visiting the Cape Town aquarium and even sidling up to a few friendly penguins.
"Bitch stole my look," she jokingly captioned one snapshot, in which she kneels by a particularly skeptical bird. The singer wears her hair back in a tight bun in an all black-and-white ensemble.
As part of her wild excursion, Rihanna also cuddled with cheetah cubs and met a giraffe.
