R&B star Rihanna caused a bit of a stir Monday in Bangor, Northern Ireland when she was asked to leave a farm where she was filming a video for her new single, "We Found Love."  The singer and her crew were asked to cease filming when farmer Alan Graham, whose land they were filming on, took offense to Rihanna's scant wardrobe, which reportedly included a pair of bikini tops and a bikini mesh top worn without a bra underneath.  Check out stills of the singer in all three outfits in the video clip below.
