Los Angeles: Suri Cruise, the nine-year-old daughter of divorced couple Tom Cruise and Katie Holmes, has stopped learning to play the guitar after having “creative differences” with her music teacher. According to a source, Suri and Katie went backstage after watching a performance of Broadway's “School of Rock: The Musical” on Tuesday to meet the cast. During the visit, the show's star Alex Brightman asked Suri if she played an instrument. To that, the famous little girl replied that she "used to play the guitar" but no longer had a teacher. “She said she was 'a very nice person' but that it didn't work out,” pagesix.com quoted the source as saying.
