So what's the secret behind their visit? Family has been a big feature already, with Nicole spending time with her mum. Also on the agenda has been a visit to Nicole’s regular Aussie church, where the family were seen attending the 10:30AM mass.
'Nicole just wants her girls to maintain links with Sydney and to keep the family as close as possible,' says a source.
Nicole has made clear she is raising her kids as devoted Catholics. She has reportedly been devout in recent years, after previously dabbling with Scientology during her ill-fated marriage to Tom Cruise.
