Uh, did anyone else get instant whiplash when they found out the news?! When we came across the PEOPLE mag article confirming that Avril Lavigne and Nickelback singer Chad Kroeger are engaged, we knew we needed to pop a Valium because... when did she and Brody Jenner break up?

Lavigne and Kroeger first crossed paths back in February of this year when he helped her pen a song for her upcoming album. And sparks must've been flying at record speed because the duo immediately entered the most hush-hush courtship since no one in Hollywood ever. "A romantic relationship blossomed as they spent time writing together," said a friend of Lavigne.

He popped the question on Aug. 8 with a 14-carat engagement ring, and let's be real, we probably would've said yes too solely on the huge rock we'd be flaunting. We kid. Kind of. But apparently, the two are pre-wedded bliss. "He makes her so happy," said a family source to PEOPLE. "Both of their families could not be more excited."

This will be Kroeger's first trip down the aisle, whereas his bride-to-be will be making her second trip. Lavigne was previously married to Sum 41 frontman Deryck Whibley, but the two called it quites in 2009. She then dated the aforementioned Brody Jenner and we're still really not sure what happened to him.
