Actress Emma Watson and William "Mack" Knight have ended their two-year romance.
Us Weekly cited an unnamed source as saying the couple broke up earlier this year.
No reason was reported.
"I'm afraid I don't comment on my client's personal life," Watson's representative told the magazine.
E! News said Watson has never publicly spoken about her tech entrepreneur boyfriend, but the pair have been photographed together multiple times since 2016.
Watson, 27, is best known for her portrayal of Hermione in the eight Harry Potter blockbuster films.
