It was one of those gossip bites in between sets. Not sure how accurate it was, but I thought I'd share.
They started with one of those "Which celebrity couple has been hiding their engagement and ring?" then took and break, then stated something like "Justin Timberlake and Jessica Behl have been hiding their engagement for the past few months and many have wondered why. Well, we now have the scoop. When Justin proposed, Jessica insisted on getting a bigger ring. Now that she's got it, she's showing it to friends and family. At the after show party for this past weekend's SNL, she was showing it off and loving the spotlight. When she left however, her hands were in her pockets, so it looks like she's not ready to show us the rock quite yet."
