Teddi Mellencamp reveals she is dating mystery older man amid stage 4 cancer battle

Teddi Mellencamp has opened up about dating while battling stage 4 cancer in a candid new interview.

Mellencamp, who was first diagnosed with melanoma in 2022 that later metastasized to her lungs and brain, has been pursuing a new romance with a mystery older man.

The star recently went on her 10th date with the man, whose college-aged children still live in his house - months after being spotted getting cozy with her ex-love Ricci Rea.

'We're going to call him Derek,' the 44-year-old RHOBH alum said on her Two Ts in a Podcast Wednesday.

'But that's the thing when you're dating and you're both parents. Like, how are you ever supposed to get past first base? I have kids in my house. He has kids in his house.'

Mellencamp noted: 'These are the things that I haven't brought up on these dates. I'm taking it slow with him. Normally that hasn't been my past.'

The nepo baby of John Mellencamp and her estranged husband Edwin Arroyave co-parent their daughter Slate, 13, son Cruz, 11, and daughter Dove, six, as well as his daughter Bella, 17, who he shares with ex Christina Mecklenburg.

Mellencamp and Arroyave have continued to share their $6.5 million Encino marital home after pausing their divorce due to her ailing health.

Tamra Judge then asked, 'How does he deal with the cancer?'

'He's pretty good about it. He's a relatively positive and logical person in general. He's older than I am,' Mellencamp said.

'But the thing that I like the most about him is he makes me laugh.'

The Bravo-lebrity and her silver fox had an early dinner date at WeHo hotspot Craig's and then he asked if she wanted to stop by a speakeasy nearby or if she was 'too tired from her immunotherapy' for her stage IV cancer battle.

'I was like, "I actually have enough energy right now,"' Mellencamp recalled.

'Then I woke up this morning and I felt like hell.'

Mellencamp - who's getting more tests in May - revealed she has one more year of immunotherapy treatments, which make her feel terrible three weeks out of the month.

The star had 'no detectable cancer' in her body as recently as last October after undergoing radiation as well as several surgeries to remove 16 melanomas on her back and plum-sized tumors on her brain.

The RHOC guest star's 13-year marriage to Arroyave reportedly crumbled after her rumored months-long affair with her horse trainer Simon Schröeder (while his wife Karli Postel was pregnant with their second child).

Postel reportedly 'found text messages on Simon's phone that exposed the affair' and they confessed when she confronted them about it.

'I've never talked about it at all, just because of the kids,' Mellencamp confirmed on The Jamie Kern Lima Show August 5.

'And I've never wanted anybody to have a guarantee whether it happened or didn't happen, but what I can say is, did I do things that hurt other people? Yes.'

The avid equestrian continued: 'To this day, does it still hurt my heart and I wonder if that's why I got cancer? Yes, like it was my payback...nothing goes without payment.'
