John Mayer proposed to Jessica Simpson?

The rumors are swirling again, this time about whether or not John Mayer actually proposed to Jessica Simpson during their recent Australian trip.  National Ledger reports on the Star Magazine report (double attribution, you love it):

The story details that before John left the U.S. for a 12-day Australian tour, a mopey but understanding Jessica told him that he didn’t have to take her with him if he thought she would get in the way, a friend of Jessica tells Star.  “John told her he had plenty of downtime built into his concert schedule so that they could see the sights.”


So if John proposed to Jessica, who's next?
