Following a whirlwind six-month courtship, Lavigne, 27, announces her surprise engagement to Nickelback frontman Chad Kroeger, 37, who popped the question with a 14-carat diamond ring. The couple first crossed paths in February, collaborating on a song for Lavigne's fifth studio album. "A romantic relationship blossomed as they spent time writing together," a Lavigne pal tells PEOPLE.
Lavigne and Kroeger tie the knot in the South of France on Canada Day, also the anniversary of when the couple started dating. "We think it's very cool that our anniversary will always be on Canada Day," the Nickelback frontman told PEOPLE in September.
