We’ve watched the Olsen twins transform from babies to young ladies, and now they are all grown up and ready to get married – let the bride wars begin!

“Mary-Kate and Ashley are trying to one-up each other with their weddings,” a close friend said. “Neither of them wants to be second, because whoever gets married first will steal all the attention from the other!“

Ashley, who has been with Justin Bartha for a year, has been chatting away about marriage and is even between Justin’s hometown of West Bloomfield, Michigan or New York City’s Plaza hotel to throw the wedding. One insider says “They are so ready!“

But Mary-Kate is ready to tie the knot, also! The actress has been dating Nate Lowman for two years and she is ready for him to pop the question. One friend says, “She would love nothing more than to have people talk about her wedding for years to come — and forget all about Ashley’s!“
