Hardly.
Compare them:
Grace was a natural beauty
She had a career, which she gave up
She earned the respect of the people from Monaco through her engagements
Charlene had several surgeries, believe me it´s quite sad how she changed herself so much
She didn´t finished highschool and gave up her swim career years ago
She must really work hard. Albert IMO is not supportive. Which is more worst. All the husbands of the Crown Princesses in Europe were supportive and caring at the time of the engagements.
But not Albert. What is going on that he changed the dates three times, changed the engagement ring, wants an outdoor wedding, don´t take his fiancèe serious.
