who is this brand new actress?

My husband ( Y ) and I saw This is 40 a few nights ago. Megan Fox is in the movie, playing, no surprise, a hypersexual character that wears little clothing. When she appeared onscreen for the first time, Y leaned over to me. 

"Is that Yasmine Bleeth?" he whispered. 

I looked at him like he was an alien.

"Yasmine Bleeth is 50. Have you not watched TV since 1994?"

Is it possible that Y has been so distracted by med school and residency that he missed the rise of Megan Fox? 

I guess if anything could make you forget this:

it would be med school.
