MSN exclusive Marcus Foster video featuring Kristen Stewart

Check out the video for Marcus Foster's new single, I Was Broken, which features a cameo appearance by Twilight actress Kristen Stewart...

London-born singer-songwriter Marcus Foster is set to release his debut album, Nameless Path, on September 26.

The 24 year-old first came to many people's attention when his song Let Me Sign, sung by his old schoolfriend Robert Pattinson, appeared on the Twilight soundtrack.

Presumably this is how Pattinson's co-star Kristen Stewart, who makes a cameo appearance in the video for latest single I Was Broken, became both a friend and a fan.
