Chad Kroeger to marry Avril Lavigne. Yes, really.

We're calling them "Chavril". Go ahead and use it, but remember that you read it here first.

Ahem... Canadian stars Chad "the Walking Penis" Kroeger and Avril Lavigne have announced that, after a whirlwind romance that almost no one (except for Mish Way) seemed to notice, they are getting hitched.

The Nickelback frontman and the, uh, Avril Lavigne frontwoman apparently fell for each other while they were collaborating on a song—no doubt a really, really good song. After quietly dating for six months, Kroeger proposed to Lavigne by whipping out his massive 14-inch.... er, that is, a massive 14-carat diamond. Which was presumably affixed to a ring of some kind. Hopefully the kind that goes on one's finger.>

This will be the first marriage for Kroeger, 37, and the second for Lavigne, 27, who was married to Sum 41's Deryck Whibley from 2006 to 2009.

A wedding date has not been announced, but when that blessed day comes, here's hoping Kroeger will serenade his bride with one of Nickelback's tender romantic ballads. Like this one:
