As Teddi noted, “It's funny that your memories are coming to my house and my memories are going to yours,” adding that her favorite event of the year was Shep's family Christmas party.

“It was like, honestly, getting into the Met Gala,” the 43-year-old recounted. “He would check the list to see if we would get in.”

Shep had his own fond memories of fun times at the Mellencamp home. “Teddi had a great house on the beach," he shared, "and we would all ride our bikes over there and jump in the pool."

Teddi—who shares kids Slate, 12, Cruz, 10, and Dove, 5, with estranged husband Edwin Arroyave—also made a point to clarify their friendship was only platonic.

“I'm one of the only people in Hilton Head Island, South Carolina that did not make out with Shep,” she told fans, to which he replied, “That's true. It's very unfortunate. I know it's one of your biggest regrets.”

As for how Teddi is recovering after going under the knife last month to have some of the masses removed, she recently started radiation on March 17 to tackle additional tumors doctors found in her brain and lungs.
