Ned Rocknroll's attorneys headed to the High Court on Thursday (03Jan13) to obtain an injunction banning the snaps from being published.
Barrister David Sherbourne argued that Rocknroll's privacy would be invaded if the images ended up in the papers, calling the shots ""innocent but naive"".
He added: ""We're not trying to hide a guilty secret.""
Rocknroll had been contacted by editors at The Sun on Wednesday (02Jan13) for comment on the pictures, which were allegedly taken in 2010.
A hearing is scheduled for Monday (07Jan13) to decide whether Rocknroll can be granted a full injunction.
Rocknroll, the nephew of Sir Richard Branson, married Titanic star Winslet in New York last month (Dec12).
