Wedding bells will definitely not be ringing again for Rossi (Joe Mantegna) on Criminal Minds.

After teasing Morgan (Shemar Moore) about tying the knot with Savannah (Rochelle Aytes) on Wednesday's episode, which is directed by Mantegna, Rossi decides to give him a word of advice. "Just don't elope," he says in the exclusive sneak peek above.

As Lewis (Aisha Tyler) correctly surmises, there is a story there. And it involves Las Vegas, the King and a particularly egregious spelling of the third ex Mrs. Rossi's name.

Watch the video above to get all the details!

Criminal Minds airs Wednesdays at 9/8c on CBS.
