That first pic, he face looks plastic. He doesn’t seem overly ‘attentive’. Same for that last pic, what with the limp arm and all.
LOL! Neti...they were just getting into the back seat when that pic was shot. How attentive can two people look when they are just sliding into the back seat of a car and they have paparazzi pointing cameras at them? As for the limp arm in the last pic, maybe that's one indicator of why she's an ex-girlfriend now. Seacrest seems to go through girlfriends pretty quickly.
You're right, though. The Australian chick does look like she's had a little too much plastic surgery. ;-)
