Rihanna recently gave an interview with Vogue and when she was asked about Drake, here's what she said:
"The VMAs is such a fan-focused awards show, so having that energy around me, and knowing the people who had received the award in the past, made it feel like a big deal. Waiting through that speech was probably the most uncomfortable part. I don’t like too many compliments; I don’t like to be put on blast. We don’t have a friendship now, but we’re not enemies either. It is what it is.
Drake apparently took offense to RiRi's comments, because soon after, he unfollowed her on Instagram to which she retaliated by doing the same. SOURCE
