Katy Perry’s cups really do runneth over. You need pie topping? Done. PG-13 playtime for Elmo? Done. Fourth of July sparklers? Done (despite most indoor fire-safety standards, apparently).

But this time, her overachieving boobs are enlisted for a cause: boosting the self-worth of young people (gay, sick, not-skinny) who feel marginalized by the world’s narrowly-applied standards of beauty and sexuality.

And if you’re keeping track, her “Firework”clip, posted below, now constitutes the third entry this month for an unofficial It Gets Better theme song by a major 2010 pop star (see also: Pink’s “Raise Your Glass,” Ke$ha’s “We R Who We R”).
