Teresa made an appearance at the opening, and an onlooker told ET that the experience was warm and positive.

"When Teresa walked into the store, Melissa immediately ran up to her and hugged her," the onlooker revealed. "She brought Gia along. Gia and her mom looked like they were having a fun girls night out. Teresa was in great spirits and was talking to all the girls."

An eyewitness also told ET, "Things seem the best it has been with them in years. Smiling, taking photos, talking."

"People seemed very impressed with the store," the eyewitness added. "It had a very good turnout, at one point they had to wait before they could let more people in. Overall, the night seemed successful. At first, when Teresa walked in, people were focused on her. About 10 minutes into the event, it was back to normal and the girls carried on as if nothing had ever happened."

"Everything is going good," Teresa told ET about how things have been since her release. "Really good."

"[It's] amazing," Gia added. "My mom is home!"
