Timberlake dubs Spears 'childhood love'

Pop hunk Justin Timberlake has downplayed his three-year relationship with ex-girlfriend Britney Spears by comparing it to a "high school" romance.

The former 'N Sync star and Spears - now engaged to dancer Kevin Federline - shocked fans and the media when they ended their romance in March 2002, when they were 21 and 20 years old respectively.
