Did Brody Jenner Propose To Avril Lavigne?

Brody Jenner and girlfriend Avril Lavigne were spotted having dinner last night at Madeo Restaurant in West Hollywood. As she placed her hand on her hip when she walked in, we could see a glimpse of a ring on her wedding finger.
Could Brody have popped the question?? What do you think? Is that an engagement ring?
