Rihanna is in London everyone!

But wherever she goes controversy doesn't follow far behind, and sure enough within seconds of stepping off the plane at Heathrow she was already causing a stir.

This time it came courtesy of a jumper she was wearing, which was emblazoned with a picture of what looked like someone rolling a joint.

The sweater in question, made by the Diamond Supply Company, zoomed in on the cannabis cigarette and she didn't seem phased about parading it in front of the cameras.

RiRis been spotted smoking the fancy fags numerous times before, and it isn't the first time she has glamorised the use of cannabis with her clothes as only a few weeks ago she was spotted leaving a restaurant in Los Angeles wearing a t-shirt showing a woman rolling a joint.

Rihanna is in the UK to discuss her upcoming fashion range with high street store River Island.

Before she jetted in from LA, she tweeted: "Off to do some River Island business #fashawn #takeof" (sic).

Bosses will be hoping her range is a lot less controversial than her choice of flight wear though.

Speaking after the announcement that the singer was to design for them in July, River Island CEO Ben Lewis said he thought she was the "perfect fit" for them.

"We are thrilled to be collaborating with Rihanna and to be the first fashion brand to work with her in this way," he said.

"Rihanna is a style icon, from street to chic she enjoys her fashion. As soon as we started to work together we knew this was a perfect fit.

"Rihanna will be designing the collection and we will be sharing our fashion experience with her to develop a range her fans will love."
