Jennifer Aniston’s boyfriend Justin Theroux is one of the writers of the “Rock of Ages” movie (it was adapted from the stage play) and they attended the premier last Friday. Right after that, they jumped on a flight to Paris and were seen hand in hand sightseeing today. Did Justin leave town to avoid reading reviews of the movie? “Rock of Ages” is being promoted endlessly – can this musical live up to obvious expectations? It remains to be seen whether we can tolerate exuberantTom Cruise as an ageing rock star.
