Dianna Agron Engaged?

Gleeks are all atwitter that I Am Number Four hottie Alex Pettyfer popped the question to Dianna Agron. True? False? Who cares—let’s play Fantasy Glee Wedding! I picture Dianna in a Grace Kelly-esque gown with a vintage ring. But hmm . . . what will Lea Michele sing for their first dance, choreographed by Matthew Morrison? Help our little Quinn get a headstart on her nuptials . . . any suggestions?
