Furniture and a friendly face! The contestants on Ellen's Design Challenge’s new season get a big surprise when Ellen DeGeneres herself suddenly appears on stage, as seen in Us Weekly's exclusive teaser.

In the clip from the HGTV series' season 2 premiere, judges Cliff Fong and Christiane Lemieux direct the competitors' attention to a revolving door, where DeGeneres is suddenly standing next to the two mattresses that are part of the next task. The 57-year-old star is an executive producer on the furniture-design competition series.

"Oh! I was looking that way, and you're over there," DeGeneres quips, explaining why she's standing with her back to the group.

To see the contestants' reactions to the prank, watch the video above.

Ellen's Design Challenge's second season premieres on HGTV Monday, January 18, at 9 p.m. EST.
