Just finished Down Under, really enjoyed this series. Agree with everything re Tzarina, she isn't an angel but she doesn't pretend to be either - what you see is what you get. Lara goes around picking her flavour of the month and shining her light on them, she definitely needs to leave the school playground mentality behind.
As for the new BD series, I can't stand Frazer he really does think he's something special. The French stew is a PITA, so loud and dramatic. She needs to go. As for the chef..... Why go on a reality TV show if you're not happy being filmed!?
