I don't follow Avril Lavigne nor do I know who's she's dating, but as I recall the last I heard something about her and who she was dating was Brody Jenner.  Well that's apparently off and has been for some time now because People magazine is reporting that she is now engaged to Nickelback lead singer Chad Kroeger.

The two apparently have been dating secretly now for about six months and Avril's rep is just now coming out with the the news that the newly outed couple are engaged and have been since Aug. 8.

The relationship apparently began in February when the two collaborated together for a song that will be appearing on Avril's upcoming album.  According to a source to People magazine, "A romantic relationship blossomed as they spent time writing together."

On Aug. 8, 37-year-old Chad proposed to Avril, who is 27, and then place a 14-carat diamond engagement ring on her finger.  So far an announcement hasn't been made on when the two plan on walking down the aisle.

This will be Chad's first marriage and Avril's second; she was previously married to Deryck Whibley, of the band Sum 41.
