I think the media has to have something to make a big deal about for each year's events and Ryan Seacrist seems to enjoy being the one to create these types of foibles -- last year it was that Angelina Jolie felt that Ryan was being rude at another red carpet event (and he was rude in my opinion!).
A good interviewer would have taken the opportunity to introduce Gary Busey (the oldtimer) to Jennifer Garner (the relative newcomer). It seemed to me like Gary greeted Laura and then Ryan said 'hey, what about Jennifer' at which Gary greeted her in the same manner.
I guess I felt that there was overreaction and Ryan is playing it up in the media for personal gain. He loves the attention.
I hope that Jennifer works up some sort of public apology and admits that it was no big deal.
