A New Hills Relationship

Are Lauren and Stephen back on?

The Hills' star Lauren Conrad has been spotted out and about with ex-boyfriend Stephen Colletti.

The Laguna Beach stars were seen at the The Grove in Los Angeles Tuesday night watching the new Iron Man movie.

According to witnesses the two appeared very 'couply'!

Could it be the original Laguna couple are back together?

Or is it all just a show, for the sake of the new series of The Hills...

Either way keep your eyes peeled, and look out for Stephen's cameo appearance on The Hills...
