Rachel McAdams was in costume on the set of Sherlock Holmes yesterday in London. Her male costars were around, but there's still only one man we want to see her with – Ryan Gosling. Very few celebrity couples have us rooting for them as much as Rachel and Ryan and a source close to them said that while they're both single, the two still love each other and for now it's a matter of timing. Also, the two remain on speaking terms with sweet Ryan even keeping in touch with Rachel's family. Ryan is concentrating on working on a record with his band while Rachel films overseas and just lined up another role, but it sounds like we don't have to rule out another amazing reunion just yet.
