Julianne Hough and RyanSeacrest launch fun unit for kids' hospital

Julianne Hough joined her boyfriend Ryan Seacrest as he launched a new multi-media centre at a children's hospital on Friday (15Jul11).

The American Idol host headed to the Children's Hospital of Philadelphia in Pennsylvania to formally open The Voice, a technology suite which enables young patients to DJ songs and conduct interviews.

Seacrest was accompanied on his charitable trip by his country singer girlfriend Hough - and she became tearful with emotion as she met dozens of sick kids who will benefit from the project.

In a post on Twitter.com, she writes, "Having a very inspirational and emotional morning meeting kids at the Children's Hospital of Philadelphia."
