Is the author of Call from an Angel and Afterwards… officially back on the market?

Are celebrities more likely to divorce or break up? Earlier this week news reports surfaced that Guillaume Musso, 51, and his partner had split up. Is the author of Call from an Angel and Afterwards… really single again?

UPDATE 20/05/2026 : This story seems to be false. (read more)

Musso spotted alone

A fan spotted Guillaume Musso walking alone, probably coming back from picking up his mail at the end of his several mile long driveway, on the afternoon of May 18, 2026. Was he all alone? “Definitely yes,” says the fan, adding that “He was wearing a large sweater and looked really cute!”

Is Guillaume back on the market?

A rep for Guillaume Musso was not immediately available for comment.

Truth or rumor, when news that the author was splitting hit the internet Tuesday (May 19), Twitter immediately exploded with pithy commentary. It seems everyone had an opinion on the matter:

“Has anyone Guillaume’s phone number?”

“So very sad… Those 2 were so great as a couple. So cute together.”

Based on the facts (Musso spotted alone with a cute sweater), is there trouble in paradise or is it much ado about nothing?
