Okay I'm embarrassed to admit I know this but I can't resist...
Rebecca Romijn: In her prime (say 5+ years ago) was one of the top swimsuit and fashion models in the world, with countless magazine covers, SI Swimsuit Editions, etc. etc. in her portfolio. Has been doing some acting lately, including the role of "Mystique" in the X-Men movies. Currently a regular on the US television series _Ugly Betty_. IIRC, she was married to John Stamos (of _Full House_ ignominy) for a while.
Jerry O'Connell: Some dude who was on a cult science fiction show called _Sliders_ a bunch of years ago, and to my knowledge hasn't done anything notable since (other than marrying Rebecca Romijn).
Anyway, Romijn is pretty much an A-list celeb (O'Connell, not so much), what with being a famous supermodel with several hit movies and an Emmy-winning TV show under her diminutive belt, so I think "famous" is a reasonable adjective. Had I not followed the link I would never have guessed at the pic either.
