Is that because she looks good?
A quick glance at her entry on Wikipedia shows that she has played a backing role in some rock projects and she had a 3 year relationship with the lead singer of the rock band 311. Led Zeppelin is a fairly ubiquitous band and I'd suspect that she's familiar with the song.
