“RHONY”’s Ubah Hassan Makes Red Carpet Debut with ‘Mystery’ Connecticut Boyfriend Oliver Dachsel (Exclusive Details)

The model opened up to PEOPLE on the red carpet about her investment banker beau at the 2023 American Ballet Theatre Fall Gala on Tuesday

Ubah Hassan has finally revealed the identity of her mystery “Mr. Connecticut” boyfriend.

On Tuesday, the Real Housewives of New York City star, 40, made her public debut with Oliver Dachsel, who is a German investment banker.

The couple were all smiles as they attended the 2023 American Ballet Theatre Fall Gala at Lincoln Center in New York City.

"It's our first time on the carpet together," Hassan told PEOPLE at the event, calling Dachsel "my boyfriend" and gushing over their shared appreciation for the ballet. "We love it, it's very beautiful. We just saw [George Balanchine's] Jewels last month, it was my birthday present."

She went on to reveal the two had been dating for "over a year" after meeting "through friends." Hassan joked, "I want to say things like, 'We met on Tinder or Bumble,' but not really."

Hassan dressed to the nines for the event, sporting a silver sequin one-shoulder gown with a thigh-high slit. She accessorized her look with a pair of silver heels and dangling silver earrings. 

Meanwhile, Dachsel, who has been dubbed “Mr. Connecticut” on the Bravo series, looked smart in a navy blue tuxedo and white shirt.

The pair held hands as they posed on the red carpet, while they were also snapped cozying up to one another inside the event.

Hassan first revealed she was dating someone during episode 13 of the RHONY reboot when she spilled the beans to her costar Sai De Silva after her husband David Craig questioned why she was single.

“I’m good,” Hassan told De Silva, 42, as she showed her pictures of her man while remaining tight-lipped about his identity.

“Since David is so curious, I’m going to show his wife what is going on in my iPhone,” Hassan said in a confessional. “It’s very delicious.”

Asked why she is keeping her relationship a secret from the rest of the women, Hassan continued, “It’s something very new and I don’t want anyone else’s energy. I just want to make decisions for myself, and Sai can keep a secret.”

However, De Silva did not keep the information under wraps and she ended up telling their costars Erin Lichy and Brynn Whitfield, who later brought up Hassan’s boyfriend in front of everyone at her birthday party.

After Hassan received a phone call from her man, Whitfield, 36, shouted across the room, “Hey Ubah, I heard you got a man in Connecticut.”

Whitfield’s Connecticut revelation hit a nerve with Hassan, who whispered to her, “If you mention Connecticut, I’m going to circumcise you.”

“The whole thing was confidential so she must have heard from Sai,” Hassan said in a confessional. ‘But for Brynn to mention a part of that I’m just like b- - - - you don’t deserve a birthday, we should take you to McDonald’s drive-thru, and no fries for you.”

During part one of the season’s reunion, Hassan confirmed that her romance was “still going strong,” while host Andy Cohen noted that he had met her other half and he was “very tall and handsome.”

“He’s the most lovely man, really, and very handsome,” added Lichy, 36, while De Silva commented, “He is so in love with her. He has sparkles in his eyes.”

‘He is the perfect counterpart to Ubah,” continued their costar Jessel Tank. “He is patient, he is loving. He kind of just looks at her like she is art in a museum.”

Cohen, 55, then asked Hassan why she was being so secretive about her relationship.

“He is very private because of his work,” replied Hassan of Dachsel, who has worked in investment banking for 17 years according to his LinkedIn profile.
