French President Nicolas Sarkozy has said his relationship with former supermodel Carla Bruni is "serious" but refused to reveal any wedding plans.
He told reporters there was a "strong chance" the media would only learn about the wedding after the event.

Appearing before international journalists in Paris, the French leader said he and his girlfriend wished to "break with a hateful tradition of hypocrisy" by making their relationship public.
"Carla and I have decided not to lie," he said, in what the French news agency AFP reports was a clear allusion to the late President Francois Mitterrand's concealment of an illegitimate daughter for years.
Mr Sarkozy has three children, two from his first marriage to Marie-Dominique Culioli, and the third by Cecilia.
Ms Bruni, 39, has a young son from a previous relationship with philosopher Raphael Enthoven.
At various times, she was also linked to men including Mick Jagger, Donald Trump and Eric Clapton.
She has made a successful career as a singer since her modelling days.
