Justin Timberlake & Jessica Biel - Are They Engaged?

Is anyone else really beginning to think that Jessica Biel and Justin Timberlake are not engaged. The only person from either side who has said anything was Justin's grandmother. Yes, grandmothers know a lot, but maybe she heard wrong. What is the point of hiding an engagement? Does Jessica need to tell someone close to her first? Having trouble coming clean? People get secretly married all the time in Hollywood but rarely are there secret engagements even with publicity shy couples. There is no real point to being secretly engaged. You don't want congratulations? Don't want people to be happy for you? Are ashamed? There has been no ring sighting and no sightings of the two of them together. Granted, Jessica got cast in a movie. Probably some producer who really hates his boss or is close to retirement. Still though, you would think there would be something by now and there has been nada.
