Queen Camilla not ruled out, Charles says

London -- The heir to the throne of the British Commonwealth, Prince Charles, says it's possible his second wife Camilla could assume the title of queen.

In an interview with NBC's Brian Williams, Charles appeared off-guard when asked about the potential status change to co-monarch for Camilla, The Daily Telegraph reported.

"That's, well … we'll see, won't we? That could be," the heir-apparent said.

The 62-year-old is the heir to his mother, Queen Elizabeth, who has made no indication of stepping down at the age of 84.

Camilla Parker-Bowles and Charles were reportedly romantically linked before and during his marriage to Diana Spencer in 1981. Diana was killed in a Paris car crash in 1997 and Charles married Camilla eight years later.

Diana assumed the title and role of Princess of Wales, but the royal family opted not to re-bestow that title on Camilla, instead referring to her as the Duchess of Cornwall, or "Princess Consort," the newspaper said.
