Chad Kroeger and Avril Lavigne blindsided us with their engagement and blinded us with that huge rock. If you appreciated the randomness of this coupling, Chavril is the way to go this Halloween.
What you'll need:
1. A fake goatee for Chad. The rest of the stuff you can probably source from your closet. [$7.99 Kmart]
2. Fake diamond ring for Avril. [$3.99 Halloween Costumes]
3. Red nail polish. (You can use it again so feel free to splurge.) [$8 Essie]
