In today’s surprise celebrity engagement news, Elizabeth Olsen is heading to the altar.

The Avengers: Endgame star, 30, is reportedly engaged to her boyfriend of three years, Robbie Arnett, according to People. (He’s widely known for being the lead singer of indie pop band Milo Greene.)

Although not much is known about the proposal, we’re not surprised they kept it under wraps, since Olsen is usually private about her personal life.

Dating rumors first started circulating in March 2017 when Olsen and Arnett were spotted together in New York City. A few months later, the pair made their first joint appearance as a couple when they attended a pre-Emmys party.

This isn’t the first engagement for Olsen. The actress was previously engaged to Boyd Holbrook (Narcos), but the couple broke off their relationship in 2014 after three years of dating.

While Olsen and Arnett didn’t reveal any details about their future wedding, we’re keeping our fingers crossed her sisters Mary-Kate and Ashley will be there, rocking matching bridesmaids dresses.
