Ex-lovers James Blunt and Petra Nemcova are struggling to avoid each other at the Cannes Film Festival - because they keep getting invited to the same parties. Blunt and Nemcova split in February (07) after a nine month romance and the You're Beautiful singer has since been linked to a string of women. When Blunt arrived at jeweller De Grisogono's party at the Hotel Eden Roc on Tuesday (22May07), he was distressed to hear the Czech model was already at the venue and refused to be in the same room as her. British newspaper The Sun reports Nemcova was also frustrated to hear of her ex's presence, saying, "Don't even talk to me about James. I just want to enjoy myself tonight." Also at the bash was Kid Rock and former Destiny's Child star Kelly Rowland.
