Elizabeth Olsen engaged to boyfriend of two years Robbie Arnett

Elizabeth Olsen is set to tie the knot.

The Avengers actress is reportedly engaged to musician boyfriend Robbie Arnett.

Sources confirmed to People magazine that the Marvel star and her boyfriend of two years are set to walk down the aisle.

The 30-year-old and her musician partner, who is the frontman for indie pop band Milo Greene, have reportedly been together since early 2017.

The notoriously private pair made their first public appearance as a couple back in September of 2017, when they attended the Gersh pre-Emmys party together.

While the pair like to keep themselves to themselves as much as possible, the Godzilla actress, who is part of the infamous Olsen clan and younger sister to high-profile twins Mary-Kate and Ashley Olsen, has previously taken to her Instagram account to share sweet pictures of her and her beau.

The Ingrid Goes West star, who plays Wanda in the blockbuster Avengers franchise and has recently confirmed new TV series WandaVision, last year uploaded an image to Instagram displaying a layout of sweet Polaroid snaps that show the couple enjoying a summer getaway together.

A few months earlier she also shared an adorable snap of the duo frolicking out in the show to celebrate her love’s birthday.

She captioned the upload: ‘Happy Birthday. I love you very much. So I’m telling instagram.’

The Avengers star has also previously opened up on the future prospect of having children with her now-fiancé.

Giving a tour of her recently renovated home to Modern Living back in 2017, the bride-to-be dropped hints at starting a family sometime in the future.

‘I was also thinking, there’s this small room upstairs, which would be good for a kid,’ she said at the time.

‘I don’t know where things will lead, but I do think about it in that way: ‘I think I could raise kids here,’’ Olsen added.

Congratulations to the pair!
