AceShowbiz - "Golden Bachelor" star Theresa Nist dressed to the nines at her and fiance Gerry Turner's rehearsal dinner ahead of their wedding. On Thursday, January 4, Gerry took to his Instagram account to share some sneak peeks at the intimate moment.

In the pictures, Theresa was seen glowing in a gold sequin dress featuring a cinched waist and a tea-length silhouette. The bride-to-be paired her sparkly gown from Mac Duggal with metallic pointed-toe pumps and a soft pink fur jacket.

One of the snaps saw Theresa posing with Gerry, who looked dapper in a burgundy blazer over a pastel button-up shirt. The former restaurateur completed his look with blue jeans and dark shoes. A tablescape with floral tablecloth, greenery and romantic candles were seen in the photo.

"What a great day leading up to our wedding day. But Jan 4th is THE BIG DAY. So excited," Gerry wrote in the caption.

The couple's wedding will be televised via "The Golden Wedding" special on Thursday on ABC. Some fan-favorite women from "Golden Bachelor" are set to attend the nuptials. Among them was runner-up Leslie Fhima and she will be joined by Kris Jenner lookalike Susan Noles, who will be officiating the ceremony.

At the wedding, Theresa will be escorted down the aisle by her son, Tommy. Meanwhile, the New Jersey native's six grandsons will take part as groomsmen and ring bearers.

Speaking with PEOPLE, Theresa previously shared that she opted for a "traditional and modern" wedding dress, admitting that "it's really not what I envisioned I would wear."

"I was presented with these incredibly gorgeous gowns from Badgley Mischka, and I was overwhelmed," Nist said. "I asked each one of these beautiful women to go pick their favorite. And then I picked three of mine, and I walked down the stairs with them. And when it was the dress, they unanimously thought this was the good gown. I think Susan was so proud because that's the one I picked out!"

As for Gerry, he went with a black tuxedo even though he initially thought about wearing a blue suit. "We talked one night, and we came to the conclusion that a black tux would look a little more formal," he revealed at the time. "And that's where I'm going, the black tux."
