London - Carla Bruni-Sarkozy, singer, former top model and First Lady of France, enhanced her celebrity status in Britain even further with a performance on BBC television in which she revealed that French President Nicolas Sarkozy takes kindly to being woken at night by her music.

"I play it at home and I disturb him with it in the middle of the night," the 40-year-old told fellow-musician and TV host Jools Holland on BBC 2 Tuesday evening.

Bruni-Sarkozy performed Tu Es Ma Came from her recent hit album, translating the title into English as meaning "You're my junk, you're my type, you're my cup of tea."

Asked what it was like mixing her roles as a singer-songwriter and president's wife, she said: "I don't really mix them up - I separate them. I play my music and then I go with my husband when he needs me."

Sarkozy was involved in her music but did not act like a critic or fan. It did not "drive him mad" when she played in the middle of the night, the singer revealed.

"I have my husband's world," she said. "It's like I just try to be with him and be cool about it and not change everything I know and my way of living. It's not so hard. It's just like playing in a film."

Bruni-Sarkozy bewitched Britain when she accompanied her husband on a state visit in March at the invitation of Queen Elizabeth II. (dpa)
