Turns out 'N Sync's Lance Bass isn't built Ford tough. Bass, who is idolized by millions of teens, got weak in the knees when his idol Harrison Ford turned up on the Toronto set of On the Line. Bass and bandmate Joey Fatone star in the new romantic comedy, which Bass also exec-produced. ''We were getting ready to shoot this scene and the director [Eric Bross] says, 'Don't be nervous, Harrison's here,''' says Bass. ''I thought it was some kind of movie term. I'm like, 'What's a Harrison?' But then I see Harrison Ford sitting there, staring at me. Not just staring at me, but staring at me acting!'' Ford was visiting his own hero, Al Green, who has a cameo in Line along with the rest of 'N Sync. Bass says Han Solo stuck around for two agonizing hours: ''I was so nervous the whole time. I could not do a thing.''
