Hibou, according to all accounts I heard, she did not attend mass but did join later in the procession and activities. Catholic or non catholic, she could have attended mass (I do that all the time) but not have communion unless it was explicitly oecumenic. In any case her dress was highly inappropriate for the occasion, especially as the prince's girlfriend. Tourists would have been permissable as being ignorant, but not the prince's girlfriend. You should listen to my elderly neighbour who attends every procession and who goes to mass to the cathedral every sunday (not her closest church, but the Monaco cathedral). To assist a religous festivity in Monaco in this kind of outfit as the prince's girlfriend and wanna be wife shows utter disrespect to Monegasque tradition and sentiment. ( my guess why she wasn't on any pics in the paper - damage control like last year) Obviously she thought it was a fun thing to attend. At least she was dressed that way. If she wants to attend these kind of events she might want to get some background info first. There is a fundraiser dinner on the weekend that Albert is supposed to attend. A lot of people that went last year said that they were not sure about going or not, because they are not willing to pay 280 Euros to watch Charlene eat. They said it is nice of Albert to have said that he'd attend, but they are not thrilled at the prospect of Charlene being there, although so far it is not official that she will tag along. To be quite honest, I wouldn't want to be in that room if you paid me 2800 Euros to attend the dinner if she was there. Having had a glance at her table manners, has put me off for a lifetime. Not an experience I need to relive.
