Some alumni of The Voice Season 7 have returned for Season 8!

Watch Sneak Peek Of Season 8 Knockout Rounds On 'The Voice'

On Wednesday, The Voice's Twitter revealed Adam Levine's former contestants Matt McAndrew and Chris Jamison have returned to The Voice this season to host Facing Off on the series' YouTube channel.

In Facing Off the two former contestants from last season are essentially putting the contestants that are heading into the Knockout Rounds into the hot seat to get to know them a bit better.

Below are videos of McAndrew and Jamison chatting with Pharrell Williams' team, Blake Shelton's team, Christina Aguilera's team and their former coach's team.

McAndrew and Jamison get up to some serious silliness as they scare Aguilera's team members.

Jamison tells Joe Tolo that The Voice host Carson Daly's "great, great, great, great grandfather haunts" the stage.

Sonic has the best facial reactions to the questions asked by McAndrew and Jamison.

Shelton's artist Kelsie May talks with them all about One Direction. She adores Harry Styles, but Jamison is "more of a Niall [Horan] kind of guy."

Thanks to McAndrew and Jamison, Corey Kent White reveals his hip-hip artist stage name -- it's Sensual Chocolate, which leaves the former Season 7 contestants pretty speechless.

Some of Williams' team, including Hannah Kirby are surprised by the Facing Off hosts since one would hide and then randomly pop out and join the conversation.

Levine's artist Deanna Johnson also falls victim to getting surprised since she and Jamison were discussing chocolate milk before McAndrew pops up from behind the couch to join in on the chat.

Watch all four teams' videos below.

Tune in on Mondays and Tuesdays starting at 8 p.m. ET for Season 8 of The Voice on NBC.
