La Joaqui stunned to find her own dancer competing on 'Popstars'

Argentine singer La Joaqui, a guest judge on Telefe's 'Popstars', was taken aback to recognize contestant Lourdes, a dancer who worked with her on three music videos. 'How did you have all these dreams and I never saw it?' she said.

Lourdes had kept her singing ambitions secret. The moment got even more emotional when her boyfriend showed up with a Sulley plush from 'Monsters, Inc.' as a good-luck charm.

Nicki Nicole, also on the judging panel, was moved and summed it up: 'I love this day.'
