They are really undercover lovers!

Eva Mendes and boyfriend Ryan Gosling arrived back at their N.Y.C hotel last night, but they must be trying to keep their relationship out of the press, because the pair made their entrance separately to avoid being photographed together!

The duo are in the Big Apple for the premiere of their new movie The Place Beyond The Pines, and it must be nice to be in a relationship with your co-star and have a date for your big night!

These two have been together for a while, so we wonder when Ryan G is going to put a ring on it?!
