Rihanna made her appearance on 'Extreme Makeover: Home Edition' along with Michelle Obama. She volunteers at the Steps-N-Stages Jubilee House where she also supports females veteran and provides shelter. Rihanna even auctioned off tickets to her concert and all of the proceeds would go back to the house. It's always nice to see your favorite celebrities being appreciative and giving back.
Here's the video (Watch the whole thing or forward to 48:55 for Rihanna's segment!)
