Darren Criss & Fiancee Mia Swier Are ABBA on Halloween!

Darren Criss and his fiancee Mia Swier are a perfect pair as Agnetha Fältskog and Björn Ulvaeus from the iconic Swedish duo, ABBA!

“Here we go again. Happy Halloween from Bjorn & Agnetha! 🎶 🎃 @abbaofficial,” the 31-year-old Emmy-winning actor captioned with his Instagram post.

Darren and Mia were spotted making their way into Podwall Entertainment’s 9th Annual Halloween Party presented by Maker’s Mark that same evening (October 31) held at The Peppermint nightclub in West Hollywood.

Also in attendance at the bash was Darren‘s former Glee co-star Chris Colfer, as well as a moth-inspired Paris Hilton and her fiance Chris Zylka.
