The shots – taken in the early hours of Thursday morning – have fuelled speculation that the 25-year-old singer and the Harlem-born rapper – who supported her on part of her Diamonds world tour – are more than just friends.
In one, A$AP Rocky – real name Rakim Mayers – can be seen smiling down at Rihanna and leaning towards the star.
In another, the rapper has a hand on her shoulder and the pair appear to be kissing.
Rihanna and A$AP have been linked in the past, but both parties denied any romantic involvement.
