Love is in the air in 2012! Many pop stars, including Miley Cyrus, Adele and Kelly Clarkson, all got engaged to be married this year!

Some proposals were more unexpected, like Deadmau5's, but we saw others coming a mile away. Miley Cyrus has been dating Liam Hemsworth since 2009, while Kelly Clarkson pretty much gushes about her fiance every chance she gets. And let's be honest, NO ONE saw Avril Lavigne's engagement to Nickelback frontman Chad Kroeger coming.

Will 2013 bring us a Kimye engagement? What about Jason Derulo and Jordin Sparks? We shall see. Until then, check out who got engaged in 2012.
