Hunter Biden’s wife Melissa Cohen soaked up the sun in a red bikini on Saturday while enjoying a beach day with friends in Brazil. The South African activist, 35, was spotted frolicking in the ocean and sipping on a coconut drink on the sand with two male pals during the afternoon outing in Rio de Janeiro. Cohen showed off her toned figure in a string bikini and cheeky bottoms, opting to leave her blonde hair loose around her shoulders.The mom appeared to be having a great time as she laughed and splashed around with one of her friends in the ocean. When she wasn’t in the waves, she was basking in the sun, alternating between lying on her back and stomach on a towel on her lounge chair.
