The New York City medical examiner's office is still investigating, but confirmed a man was found dead at Trump Tower.
Shields, 51, was found dead this morning in his apartment by his assistant who tried to administer Narcan for an opiate overdose but he was unsuccessful.
After knowing each other for more than three decades, Frankel and Shields started dating back in 2016, but their relationship was a complicated one.
Bethenny Frankel's boyfriend started the binge that killed him Thursday night and realized he was in trouble.
"We are all heartbroken". The Office of Chief Medical Examiner of the City of NY spokesperson told E! "Dennis was, and will always be, the love of my life", Shields' ex-wife Jill said in a statement. He was an influential figure not just to the Skinnygirl Cocktails CEO, but to her daughter Bryn Hoppy, 8, as well.
As for Radziwill, she appeared on six seasons of RHONY and left the show in July to go back to journalism and producing.
Bethenny recently opened up about her relationship with the banker during an interview with Steve Harvey on his talk show, although she didn't name him.
Frankel has not commented on his passing.
