The new season of Extreme Makeover: Home Edition premieres this Sunday at 6pm Evansville time on News 25. This week, perpetual yelling machine Ty Pennington and the team look to build a new home for a woman and her son who offer housing to homeless female veterans. As they often do, the team has recruited two big name celebrities to help the effort, First Lady Michelle Obama and Rihanna.

In the clip below, a group of volunteers get the opportunity to meet Rihanna backstage before a performance on her recent Loud tour.
