Bruni told the Liberation newspaper that she would be unable to "take part in the official trip with the president," as she was not yet married to Sarkozy.
However, she added, marriage was "in our plans."
Bruni also told the newspaper that she had sent a "collective text message" to all her friends, putting an end to the recent "storm of madness," referring to rumors that she and the French president were already man and wife.
The French newspaper L'Est Republicain had earlier said that the couple had 'secretly married' last week at the Elysee Palace. The French media had subsequently been full of speculation that Bruni and Sarkozy would use the president's forthcoming trip to India as a honeymoon.
The possibility of Bruni accompanying the divorced French president during his official visit to New Delhi on January 25 had meant a real headache for the Indian authorities as this could have been a challenge to the traditional protocol for visits by heads of state.
Meanwhile, an announcement by Le Journal du Dimanche that the couple is to marry on February 8 or 9 before Sarkozy's state visit to Britain in March meant good news for the U.K. officials. If Sarkozy and Bruni had decided to visit Britain together, the Queen would have had to offer the French leader and his girlfriend separate bedrooms at Windsor Castle.
During his latest visit to Saudi Arabia, Sarkozy was reportedly requested by his conservative hosts to leave his girlfriend at home.
Sarkozy, 52, who divorced his second wife Cecilia in October last year, told a news conference in early January that his relationship with 40-year-old Bruni was "serious" and said he planned to marry her.
Sarkozy and Bruni met in November, shortly after his divorce. Since then, their relationship has been the subject of obsessive coverage and speculation by world media.
The French website 20minutes.fr has even reported that Bruni is pregnant with Sarkozy's child, although this has yet to be confirmed.
