The Olsen sisters will be making the wedding headlines this year as Mary-Kate, Ashley, and Elizabeth are reportedly walking towards the altar before 2014 ends.

According to a source for OK! Magazine, this year will be a huge deal as the Olsen sisters have announced and discussed their plans for tying the knot with their own significant others.

While 28-year-old Mary-Kate made an announcement that she will be exchanging wedding vows with Oliver Sarkozy, twin sister Ashley has also been going over her own marriage schemes. Meanwhile, younger sister Elizabeth, 25, has also made her engagement plans public.

Last August 3, Ashley was spotted and photographed leaving her Manhattan pad with her boyfriend, Bennett Miller. The couple has been together since January when Ashley was introduced to the 47-year-old 'Moneyball' director by mutual friends.

They even went together and stood side by side at the funeral of Bennett's good friend, award winning-actor Philip Seymour Hoffman, in February.

While the former 'Full House' star has been known for seeking long-term relationships, OK! Magazine has reported that her relationship with her director boyfriend is "moving at light speed."

"They're talking marriage. She wants to spend the rest of her life with him," the insider for the publication said.

Still, Ashley's twin sister Mary-Kate had been the first to announce her plans of getting hitched. Last February, her 45-year-old beau popped the question with a vintage Cartier ring worth a whopping $81,000.

"Her family were initially hesitant about his intentions, but they realized how well they work together and how happy he makes her," added the insider.

After only two weeks, Elizabeth followed suit and announced her engagement plans with Boyd Holbrook. The couple met on the set of their indie movie "Very Good Girls" in 2012 and became a romantic pair.

Referring to her wedding in June, Elizabeth has revealed that she will let Mary-Kate decide on the date and that she is not stressing over the day that she exchanges wedding vows with her 32-year-old beau.

The twin sisters have recently designed their first wedding gown for close pal and stylist Molly Fishkin and are expected to work together again for Mary-Kate's and Elizabeth's own dresses.
