Rosie Huntington Whiteley is tower over the shortie Shia LaBeouf

Actually, they are almost the same height (he's actually a smidge taller). Check their bios on IMDb. Shia is 5ft 9¼ and Rosie is 5ft 9.

Then again, he was wearing regular shoes while she wore high heels through much of the movie, making her appear taller lol.
