Yeah its a scene where Shia LaBeouf goes out partying or celebrating with his colleagues to a club and Britt comes up showing her interest in him.
Its a 30 seconds or so scene but it appears a bit amateur-ish and forced cause even though shes all glammed up wearing sexy clothes shes too much of an elegant and aristocatic appearance to really convice in the "I want you" role, if you know what I mean.
I just watched Transformers 3 (well, I wouldn`t have liked to, but it was my bf`s choice). Rosie wasn`t exactly talented there, it was all about her looks. Luckily she didn`t speak a lot I wouldn`t predict glamorous acting career for her.
