Whoa Canada!  The two kept the relationship quiet, that few even knew they were dating.  Now after 6 months, the Canadien rockers are engaged to be married.  Lavigne 27 and Kroeger 37, first got together in February to write a song together.  On August 8th, presented Lavigne with a 14 carat diamond sparkler.  Talk about a bombshell.  If they have kids, he or she will definately get lots of music talent!
