Ubah’s companion Oliver looked good in a tuxedo at the gala.

Oliver, the cryptic “Mr. Connecticut” from the Bravo series works as the CEO of a large financial institution in New York.

While he’s been keeping a low profile and avoiding the spotlight, viewers spotted the dapper Oliver with Ubah in the VIP area at the RHONY season 14 premiere party in July.

Glamorous Ubah introduced Oliver to Bravo executive Andy Cohen, 55, and several of her co-stars, including Sai De Silva, at the invitation-only launch party.

Andy recalled their meeting on an October 8 episode of Watch What Happens Live, describing Oliver as “handsome, strong and yes, impressive.”

Chron has seen footage of Oliver mingling with Andy, Ubah, Sai and Erin Lichy at the event.

A source told the Chron that the happy couple were “inseparable” throughout the night, despite trying to be discreet.

“I assumed he was her husband because I didn’t know at the time that she was pretending to be single on the show,” the source said.

“They were together all night. “It wasn’t like they were making out, but they never left each other’s side, they giggled a lot and she seemed excited to introduce him to people,” they continued.

“She was clearly very happy. “Obviously it was a private party, but I got the feeling she was comfortable having him there.”

The couple was spotted taking photos together at the event, but they hired a private photographer to avoid the pictures being made public.

Chron has contacted Ubah, Oliver and NBC for comment.

NBCUniversal is the parent company of Bravo, which airs The Real Housewives Of New York City.

Ubah’s love life became a hot topic towards the end of RHONY’s fourteenth season when Sai told Erin that Ubah was in a relationship, even though Ubah presented herself as single on the show.

Erin then told the news to her co-star Brynn Whitfield, who later revealed the secret relationship in the show’s final episode by shouting “Ubah!” I heard you have a husband in Connecticut!’

In the end, Ubah stormed out of the party in a huff, complaining that their romance was “confidential.”

Since the episode aired, the hot sauce entrepreneur has been more open about her love life, confirming on Watch What Happens Live that she is “very much in love and happy.”

Ubah also said the relationship was “still good” at the Season 14 reunion, where Cohen gushed that Oliver was “very tall and handsome.”

Ubah has hinted that Oliver might appear with her on the next season of RHONY.

“Someone wants to know if I’m bringing my husband on season two,” she said during an Instagram live stream this week.

“I’m still negotiating,” she smiled, before cheekily looking at someone behind the camera.

The dashing Oliver served in the Bundeswehr for a year before attending a private business school in Vallendar.

From there, he attended Columbia Business School in New York and then spent a decade working his way up the corporate banking ladder.

Today he is the managing director of a large financial institution specializing in mining and investment banking.

In his Linkedin profile, Oliver boasts that he has advised on “over $40 billion in completed M&A, debt and equity market transactions” since 2006.

Although he works in the banking industry, Oliver has a great philanthropic and charitable side.

He has previously worked with nonprofits to bring clean water to people around the world and is a board member of All Hands And Hearts, which supports disaster relief.

Meanwhile, producers are currently in the process of casting for the fifteenth season of The Real Housewives of New York City.
