Avril Lavigne is engaged to Chad Kroeger of Nickelback

Andre Agassi and Steffi Graf got married and had a kid, and so did Nadia Comaneci and Bart Conner, which sounds like some Nazi program to create the worlds best tennis player or gymnast.

This is the exact opposite of that but with music.

Avril Lavigne and Nickelback frontman Chad Kroeger's relationship has been so quiet that few even knew they were dating. Now, after a six-month courtship, the Canadian rockers are engaged to be married, Lavigne's rep tells People exclusively.
Lavigne, 27, and Kroeger, 37, first got together in February to co-write a song for Lavigne's upcoming fifth studio album.

Well of course it was quiet. Would you tell anyone if you were dating Avril Lavigne or Chad Kroeger? I wouldn't even acknowledge being in the same room with them. You'd have to put a burning tire around me to confess to dating one.
