YouTuber Siera Bearchell has made her Miss USA 2018 predictions… and she's an authority on the topic! Siera was crowned Miss Universe Canada in 2016, and she has actually crossed paths with some of this year's Miss USA contestants during prior beauty pageants. Ahead of this year's big show — which airs live on Monday, May 21 — Siera has named her top five in a YouTube video.

That said, this beauty queen is not completely confident in the picks you see below, especially because the Miss USA organizers didn't post the contestants' videos online this year. "I have no idea what the result is going to be," Siera said. "It's going to be super interesting. I'm excited to watch it on Monday because I think there's going to be a lot of surprises."

Bryce Armstrong

Bryce, aka Miss District of Columbia, has accomplished a lot in her 21 years! She has already kicked off her own cake-baking business, for example, and she volunteers with an organization that feeds the homeless in our nation's capital. If she wins Miss USA, she'll be the third consecutive winner from D.C.!

Kelley Johnson

Speaking of lifesavers, this Miss California is a doctoral student and a registered intensive care unit nurse. Plus, the 25-year-old has given more than 65 keynote speeches over the past two years, so you know she has good stage presence.

Alexandra Harper

Is there anything this year's Miss Tennessee can't do? The 25-year-old is a writer, business owner, a personal stylist, a sales executive, and a social media manager. She's also an ambassador for Second Harvest Food Bank and the director of a documentary for the nonprofit Healing Housing. Could Alexandra add Miss USA to that lengthy resumé?
