Speaking exclusively to omg! at the VERY freezing but very amazing Les Miserables world premiere, Amanda told us that she just loved working with Eddie.
She told us: "Oh he's a sweetheart! He's so sweet that I feel like there must just be some sort of devil inside of him!"

And he can sing! Yep, Mr Redmayne gets even more incredible that we could ever imagine in Les Mis and shows us that he is far more than just an amazing actor.
"He is IN-CREDIBLE! It's like he is an accomplished singer but he just never told anyone... he made me want to dub myself!"
This got us thinking, Amanda is not the only one to rave about Eddie. Remember when he briefly dated Taylor Swift earlier this year?
Yep, before Harry Styles, Taylor had her eye on another Brit - Eddie!
Taylor even auditioned for the role of Eponine in Les Mis, however missed our on it to Samantha Barks who is also featured in the above vid.
However, Taylor and Eddie were not meant to be and it was reported that they split due to 'long distance'.
Les Mis is out in January and trust us, you need to see this: it is amazing and will almost definitely win about a million Oscars.
