Teddi Mellencamp, 45, goes Instagram official with boyfriend PJ Conley, 31, after introducing him to her family

Teddi Mellencamp went Instagram official with her 'Valley Guy' boyfriend PJ Conley after they attended her famous father John Mellencamp's concert at the Hollywood Bowl in California on Monday.

At 45, the RHOBH alum is 14 years older than the financial benefit analyst, who sported a Coors cap on their group date that included her estranged husband Edwin Arroyave, their children and her former RHOBH co-star Kyle Richards.

'Isn't he cute?' Mellencamp asked on her Two Ts in a Podcast Wednesday.

'He's a nice guy and he's funny,' she shared. 'He got along effortlessly with the fam - my brothers, my sisters, my dad. My dad met him, but then didn't say anything straight away. He just was like, "Hi, nice to meet you." But I just kept it moving because I was with so many people.'

The self-described 'cougar' continued: 'And then yesterday, my dad comes over. He lights up a cig. "You gonna try not to tell me that was your guy that you introduced me to? You thought you were just gonna slip that in?''

Conley, who has yet to repost any of Mellencamp's loved-up footage, is a former Mormon missionary pursuing a master's degree in business at USC Marshall.

'He's not from [the San Fernando] Valley, but his hometown has a valley in it, so it still counts,' Mellencamp said of her new beau.

In April, Mellencamp dated an older man she called 'Derek' who had college-aged children after splitting with producer Ricci Rea last year.

Meanwhile, the nepo baby's 49-year-old ex Edwin Arroyave was happy their four children - daughter Slate, 13, son Cruz, nearly 12, daughter Dove, six, as well as his daughter Bella, 17 (with ex Christina Mecklenburg) - were 'finally old enough to understand just how extraordinary their grandpa @johnmellencamp is.'

'I never had the chance to meet either of my grandpas. They both left their families, so I never got to make those kinds of memories,' Arroyave wrote on Instagram.

'That's why seeing my kids share this experience with their grandpa meant so much to me. They gained a core memory I never got to have. If you don't come from a rich family, a rich family can come from you, and I don't just mean financially.'

Arroyave concluded: 'True wealth is built in every area of life - faith, family, fitness, finances and fun. That's the legacy I hope my children learn in this life.'

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

The Bravo-lebrity's 13-year marriage 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).

Health-wise, Mellencamp is still receiving weekly immunotherapy treatments while in remission with her stage IV cancer battle.

The RHOC guest 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 Daily Mail has reached out to Mellencamp's representatives for comment but did not immediately hear back.
