Bikini-clad Carla Bruni shows off her pregnancy curves in all their glory as she holidays with Sarkozy

Carla Bruni has been keeping quiet about her pregnancy since rumours of her expectant state first emerged in April.

But it looks like the French First Lady isn't hiding her burgeoning belly as she holidays with her husband Nicolas Sarkozy in the south of France.

The former supermodel, 43, showed off her pregnancy curves in all their glory as she relaxed on the beach in a brown bikini.

Bruni and her husband, 56, are currently holidaying on the island of Fort de Bregancon, a presidential retreat on the Mediterranean coast.

After arriving last week, the pregnant brunette has been taking things easy, while her husband has been spotted cycling around the fort and driving his wife in a golf cart.

On Sunday afternoon, the couple cosied up together on the beach and looked very affectionate.

And as the summer temperatures rose, they decided to cool down with a dip in the sea.

But already sporting quite a sizeable bump, Carla need help from her husband as he hoisted her to her feet.

The supermodel clearly found it entertaining that she was struggling to get up without help and giggled with her husband.

While Bruni has not yet officially confirmed her pregnancy, she is believed to be five and a half months pregnant.

Some reports have claimed the singer/songwriter is expecting twins, but the couple haven't confirmed or denied how many babies they are having.

Sarkozy's father Pal Sarkozy, 82, told German newspaper Bild recently: 'Neither wants to know the gender beforehand, but I'm certain it will be a girl, and beautiful like Carla.'

The baby will be the first together for the couple, who married three years ago following a whirlwind romance.

Private joke: The couple appeared in good spirits as they laughed and cuddled in the surf

Bruni has a 10-year-old son Aurélien from a previous relationship to philosophy profressor Raphaël Enthoven, while Sarkozy has three sons from his first two marriages.

Sarkozy is father to Louis, 14, from his second marriage to Cécilia Ciganer-Albéniz, and Jean, 25, and Pierre, 26, from his first marriage to Marie-Dominique Culioli. 

The couple's unborn child will become an aunt or uncle once it's born after Sarkozy's middle son Jean made him a grandfather last year.

Jean, a regional councillor in the French region of Neuilly-sur-Seine, and his wife Jessica Sebaoun-Darty welcomed a baby boy named Solal together in January 2010.

Miss Bruni and Mr Sarkozy began their whirlwind romance after advertising tycoon Jacques Seguela brought them together on a 'blind date' at a dinner party in November 2007.

They married just three months later at a private ceremony in the Elysee Palace on February 2, 2008.
