Will Smith loves the kids. The father of 3 made a surprise appearance at an assembly for A+ students at a school in London on Monday. When Smith launched into an acapella version of the Fresh Prince of Bel-Air theme song, the audience of school girls went nuts. Smith was in Europe with his son Jaden Smith, the opening act for pop singer Justin Bieber during his 4 night stand at London's 02 Arena.
