Avril Lavigne could be getting her happy ending after all.
The pop-punk princess is engaged to her longtime boyfriend and fellow rocker, Deryck Whibley of Sum 41, her Website announced Tuesday.
"Avril and Deryck are very excited and they want to thank all of their fans for their best wishes," said a posting on the site.
Whibley, 25, popped the question to Lavigne, 20, over the weekend while in Europe, according to Us Weekly, which first reported the engagement.
No word yet on when they plan to tie the knot. It will be the first marriage for both.
The betrothed musicians hail from the Canadian province of Ontario; they were friends before they began dating in early 2004 (when, coincidentally, Lavigne was no longer a minor).
In a May interview with Us Weekly, Lavigne said, "I hope to make a few more records, get married and have a couple of kids."
Although she and Whibley recently bought a house together in Los Angeles' tony Bel-Air neighborhood, she told the magazine she would prefer to raise her children in Canada. The "My Happy Ending" singer also has a home in Toronto.
Lavigne, who previously dated former bandmate Jessie Colburn, is preparing to launch a North American tour in support of her seven-times-platinum Arista release, Under My Skin. The amphitheater jaunt begins July 12 in Hamilton, Ontario.
Whibley, who has previously been romantically linked with Paris Hilton, is currently on the road in Europe with his multiplatinum-selling punk band in support of their latest, Chuck.
