The public's appetite for those "Oops! ... I Did It Again!" moments involving pop princess Britney Spears shows no sign of waning as she scooped the number one celebrity viral video this year.
A clip of Spears burping and talking incoherently about her belief in time travel was viewed over 3 million times to take top spot comfortably, said ViralVideoChart.com on Monday.
Live TV footage of Spears' former husband Kevin Federline apparently getting a text message informing him the pop singer had filed for divorce was second with nearly 2 million hits.
