The celebrity world was shocked when news hit that George Clooney and longtime girlfriend Elisabetta Canalis split up--but no one may have been as surprised as Canalis herself!

One of the model's close friends, Chi magazine editor Alfonso Signorini, opened up about the couple's relationship and breakup.

"It's all over," Signorini said on Italian TV show 'Rai Uno' Thursday [via UsMagazine.com.] "It has come as a real surprise to me. They were getting on really well."

Just last week, the editor spent the day with Canalis and things appeared fine. "She must have had about 60 text messages from George! She was so excited about meeting him as he had a few days off from shooting his film in London," he recalled.

As for the split, he revealed: "From what I know it was him who dumped her and she stormed out of the villa. I've tried to get her on the telephone but it's switched off."
