What has added more to the speculations is the reports that RiRi has given up smoking and drinking altogether. Rumor has it that the barbarian singer is avoiding events and parties where she is required to smoke and drink.

Further more, the rumors are ripe that RiRi has been purposely sipping on water and healthy drinks instead of hard drinks and weed.

"Rihanna refused to attend the official after party on Drake's tour because there would be too much alcohol and weed smoke there. So she went back to the hotel room instead," a source told the publication reported Showbizspy.

It's no secret that he belongs to her and she to him but as far as them coming out and being like, 'Oh hey, look at us, it's official,' who knows when that's going to happen?"
