"The footballer Ronaldo and the television presenter Daniella Cicarelli officially inform that they are separating and they reserve the right not to give any more details about the episode," said a statement issued by a spokesman for Cicarelli.
The couple threw the party, which cost an estimated 700,000 euros ($899,200), near Chantilly on February 14.
Although it was billed as a wedding, Ronaldo could not marry 23-year-old Cicarelli because he had not been divorced for a full year from his first wife, Milene Domingues.
Ronaldo and Domingues were married in 1999 and have a child named Ronald.
