'Got my kush rolled and glass full!' Rihanna clears up confusion about what she's been smoking with cannabis quote on Twitter

She has been spotted over the past few days puffing on a suspicious looking cigarette during her Hawaiian holiday.

And yesterday Rihanna appeared to clear up exactly what she has been smoking by quoting some lyrics from rapper Drake's song Up All Night on her Twitter page.

She wrote: 'Kush rolled, glass full... I prefer the better things!' Kush refers to a type of cannabis found mainly in Afghanistan, Pakistan and India.

The singer, who features in a new Armani campaign, seemed pensive as she waded out into the sea in a skin-tight hot pink dress, which she was wearing over a green and black bikini.

She splashed around in knee-deep water while clutching the hand-rolled cigarette, after taking a walk earlier in the day.

The brown papered roll-up looked remarkably similar to a 'blunt', which is slang for a marijuana filled cigar. The type favoured and popularised in hip-hop music.
