Amal Alamuddin's 'Cinderella moment' at bridal shower

Amal Alamuddin George Clooney's Lebanon-born bride-to-be was spotted in a long red gown heading off to her own soiree at the fresco-adorned

Aman hotel with close friends including Ellen Barkin -- who threw the 36-year-old human rights lawyer a hen party several weeks ago.
In a Cinderella moment, Alamuddin lost her shoe after the stiletto heal got caught in a gap in the slatted floor in front of the hotel, but she recovered in style.

Matt Damon, Cindy Crawford and her husband Rande Gerber -- tipped to be Clooney's best man -- were just a few of the stars in Venice for the wedding, with Brad Pitt, Angelina Jolie and musician Bono tipped to follow on Saturday.
