Elizabeth Olsen Opens Up For First Time About Her Engagement

May 1, 2014 — -- Elizabeth Olsen is finally opening up about being engaged to actor Boyd Holbrook.

The "Avengers: Age of Ultron" actress, 25, said she couldn't be more excited about tying the knot with the man she's been dating for the past two years. They met on the set of "Very Good Girls" in 2012.

"I'm relaxed about it, but I am excited and planning ideas because it's fun - It's just like throwing a party to celebrate life," she told Marie Claire UK for its June cover. "I love being in a relationship a lot."

The reports that Olsen and Holbrook were engaged spread in March, just days after reports broke that sister Mary-Kate was also engaged to beau Olivier Sarkozy. Elizabeth joked with Marie Claire that there won't be a double wedding with her sis.

"No, I just told her she gets to pick a date first!" she said.

While her older sisters -- the Olsen twins, 27 -- might be successful actresses and businesswomen, Elizabeth said they actually kept their little sister "grounded" when she was growing up.

"Because my sisters were so grounded, it helped me be grounded," she said. "They never got caught up in things. I did live a charmed life. We got to go on vacations and lived in nice homes and I got to play club volleyball and ballet, which you don't realize as a kid are expensive. My mom would say things like, 'Lizzie, we are not the Rockefellers!' That put things into perspective."
