She also got in a selfie with the smiling birthday boy and her beau as well, captioning the image, ‘Happy birthday #Champ @floydmayweather. Would only fly 18 hours for your #Birthday’.

Around Thanksgiving of last year, Mariah and Bryan were spotted kissing in Hawaii, after speculation arose that the two were dating following a broken engagement.

In an interview with Rolling Stone, the We Belong Together songstress discussed, only slightly, her relationship with her much-younger beau.

‘I don’t think we’re being public in a way that my relationships have been public before,’ she began.

”I really don’t. To me, the best thing of this is to keep it a little more private. But I’m not going to not go places with him and enjoy our lives because everybody thinks, ‘Oh, it’s too soon!’ kind of thing. We all saw the freakin’ show. This is not a surprise.’
