The Wanted star Tom Parker is facing a fine from officials in Colorado after he allegedly defecated into a plastic bag and threw it out of his tour bus window. The Walks Like Rihanna singer pulled the prank while in the U.S. with his bandmates and faces a penalty of up to $500 (£333) for littering, which is considered a class two petty offence in the state. Parker avoided being penalised by crossing the state line the following day, but bandmate Jay McGuiness is convinced he will be forced to pay the fine eventually, telling Britain's Daily Mirror, "I am going to try to avoid Colorado right now but if we do go (back), Tom needs to get $500 ready. That was the most expensive passing of a number two (Tom) will ever have." The revelation comes just days after the singers were accused of drenching a hotel guest by throwing Champagne out of a window at the Marylebone Hotel in London while celebrating McGuiness' birthday last week (beg22Jul13). Police were called, but no charges were filed.
