News broke last month that Joanna had filed for divorce from her husband of less than four years, Romain Zago.Ī source tells us Joanna is very happy for her sister and seemed “unburdened” by personal issues during the trip.

Joanna, 38, was overheard toasting her 31-year-old sister, saying, “To Marco and Marta – and being with one man, forever!” The bachelorette party began with a gourmet meal at MB Steak at the Hard Rock Hotel & Casino and switched gears when the ladies headed to the sexy Thunder From Down Under show at the Excalibur.
