Pop star Rihanna, center, during filming in the New Lodge area of North Belfast, Northern Ireland, Tuesday, Sept. 27, 2011. Northern Ireland farmer Alan Graham says he doesn’t know who Rihanna is but she must keep her top on while performing on his land. Graham says he enforced a dress code as he watched Rihanna shoot a video Monday in his wheat field in Bangor, east of Belfast, for her new single, “We Found Love.” She’s in Northern Ireland this week to perform three concerts.
