Ananova:

Avril Lavigne and rocker boyfriend Deryck Whibley are engaged.

The Canadian rocker said yes when Whibley popped the question in California at the weekend.

The couple are said to be blissfully happy and Lavigne has been showing off her sparkling ring to friends.

One said: "Avril has had a grin on her face ever since. She's really excited. People tag her as this miserable teenager but she couldn't be happier right now.

"She told her mum straight away and she has been totally buzzing. They haven't set a date yet but they want to walk up the aisle next year."

The pair started dating earlier this year, says The Sun.
