Shannon teases her "new, new guy" to her friends at the soirée in the above preview for the upcoming episode. "But you know what's interesting? He had a child with Tammy Knickerbocker, who used to hang out with this group of people," Shannon reveals in the clip. "So he knows a lot of people here."
That's right, Shannon was dating RHOC alum Tammy's ex Duff Evans at the time. Tammy appeared in Seasons 2 and 3 of RHOC, in addition to popping up on the show over the years. There's even a flashback to when Duff appeared on RHOC with Tammy in 2008 in the clip, along with their son, Ryley.
Vicki's brother Billy Steinmetz recognized Duff in the clip, and Vicki and Tamra Judge both seemed pleasantly surprised to see him at the fête.
However, things did not work out between Shannon and Duff, either. Shannon would eventually go on to meet John Janssen, whom she has been dating for the past several months.
Check out the whole episode when it airs December 17 at 9/8c, and catch up on this season of RHOC through the Bravo app.
