We find it difficult to imagine Twilight star, Kristen Stewart with anyone other than her co-star Robert Pattinson.

But we just stumbled across a photograph of her ex-boyfriend Michael Angarano having lunch with some friends in Beverly Hills and it all came back to us!

Kristen and Michael has been dating for over three years when she began filming Twilight and it was soon clear for everyone to see that Rob and Kristen shared an instant chemistry.

As much as Michael insisted he and Kristen were as strong as ever, we all knew their split was inevitable.

Can you imagine Kristen with Michael now?! We just couldn't see them together. It was Robsten from day one!

Kristen was smitten with Rob from day one...
