Superstar Keri Hilson paid a visit to The Voice studio at the Children’s Hospital of Philadelphia (CHOP) last Friday. While at The Voice, Keri participated in an interview in which she discussed what inspires her while she’s writing songs. The Grammy nominated recording artist also talked about some of her collaborations with other big name performers like Soulja Boy, Kanye West and Chris Brown and told the kids what it’s really like to work with some of today's hottest and most popular musicians. Hilson also gave the audience a sneak peek into what’s coming up next for the singer. We’re so excited to hear what songs she comes out with! The highlight of Keri’s visit was definitely when she took it upon herself to teach the patients of CHOP her “Pretty Girl Rock” dance. They all moved and grooved to the catchy beat - The Voice studio was really rocking. So fun! After that, Keri took pictures and signed autographs for every child there, giving them yet another photo opportunity with a big name celebrity at The Voice! The Voice studio continues to bring joy to the lives of these children with an ever growing list of star studded visitors and performers. Check out the photos below!
