Prince William said Thursday that he and Kate Middleton were still "working on" a name for their new baby son.
But there's a lot of chatter that their third child, born on Monday, is called Prince Albert.
A page on the Royals' website reportedly listed the name on a thread that read "access denied."
Albert is now the favorite of bookies, with its odds plummeting to just 4 to 6. Arthur is also an often-mentioned name, with its odds listed at 6 to 4.
The names of George and Charlotte, the couple's elder children, were announced two days after their births.
The Prince and Princess of Wales, Charles and Diana, waited a week before releasing William as the name of their firstborn son.
