‘Selling Sunset’ stars recall their breakups with Peter Cornell 

When it comes to finding out about Cornell’s infidelity, Quinn and Hernan’s versions of the story differ. “I dropped my friend off for lunch; my friend was the one who saw you guys walking down the street,” Quinn tells Hernan during their one on one in episode 6. “I pulled my car next to your car and said, ‘Hey, I don’t know what’s going on. You can contact me. I’ll send you screenshots.'” At the time, Quinn and Cornell were allegedly engaged. 

Hernan’s story is different. “I found out about [Quinn] the day that I met her. It was not pleasant,” Hernan said. “I was leaving the gym with who I thought was my boyfriend and she pulled up with her friend and was like ‘Who the f***’ is this?’ and started screaming ‘This is my boyfriend.'” According to the Emma Leigh & Co. owner, Cornell proposed to her after he and Quinn broke up.

“Everything that’s coming out of her mouth is bulls***,” Hernan tells cameras in the. episode. “I would not describe her banging on my windows as calm. She was 100% reinventing the story, creating her own narrative, which is what she’s famous for.” 

‘Selling Sunset’ star Heather Rae Young also allegedly dated Peter Cornell 

As revealed in Selling Sunset Season 4, Quinn and Hernan weren’t the only women from the Oppenheim Group to date Cornell. Their fellow real estate agent and co-star Heather Rae Young also dated him in the past. 

“It wasn’t even a boyfriend, it was so short-lived,” she says during the new season. “Why is [Quinn] trying to bring these things up years and years later?” Young asks her now-husband Tarek El Moussa in Selling Sunset Season 4, Episode 10. 

The more Cornell’s past relationships are discussed in season 4, the more frustrated Hernan, Quinn, and Young become. Watch all 10 episodes of Selling Sunset Season 4 on Netflix now.
