Cristin Milioti has landed one of the most sought-after roles on network television, as the actress was introduced as The Mother on last night's How I Met Your Mother Season 8 finale, leaving many to wonder:

Who is Cristin Milioti?!?

The Tony and Grammy Award-nominated actress concluded her run on Broadway's Once in March; has appeared on episodes of 30 Rock, The Sopranos and The Good Wife; and will share the screen with Leonardo DiCaprio in Martin Scorsese's The Wolf of Wall Street.

"It was a pretty big umbrella to fill, casting the title role in a series that's been on the air for eight years," co-creator Carter Bays said in a statement. "And yet Cristin Milioti is, against all odds, exactly what we were looking for. She made us laugh on 30 Rock, she made us swoon in Once, and her ukulele skills are no joke.

"We're thrilled to welcome her to the How I Met Your Mother family, and look forward to getting to know her – and the character she plays – much better in the coming final season. And to all the fans, on behalf of all of us writers, cast and crew: Thank you for sticking with us on this wild journey. Our ninth season will tell the epic story of the longest wedding weekend ever. We hope you like it. Next stop, Farhampton..."
