Chelsea Houska's daughter, 6-year-old Aubree, can't wait for the Teen Mom 2 star to walk down the aisle with fiance Cole DeBoer.

During last night's Teen Mom 2 season seven finale, Houska and DeBoer spoke of their upcoming nuptials after giving Aubree her first look at DeBoer's wedding band, which was made of wood, antler and gold.

"Do you know that when we get married Cole wears a ring to?" Houska asked her daughter. "You want to see his ring?"

After a moment of excitement, Aubree paused and asked, "How come he's not wearing it?"

"He doesn't wear it until after the wedding," Houska responded.

"Then how come you wear yours?" Aubree then asked.

"When you get engaged, the girl wears the ring and then when we have the wedding, I get another ring and Cole wears a ring," Houska explained.

Later in the scene, Houska asked Aubree, "What are you going to do at the wedding?

Her response? "Dance!"

During Houska and DeBoer's upcoming wedding, Aubree is expected to play a major role. As Houska explained to PEOPLE Magazine earlier this year, Aubree will "be more than a flower girl – I've been calling her my mini maid of honor."

"I have a friend who's the maid of honor but I wanted her to include Aubree in all the stuff possible, and I want her to feel like she has an important role," Houska explained.

As for more children, Houska hopes to expand her family soon after her wedding.

"We're just going to get through this wedding, and then hopefully have some babies!" she said. "I feel like I want three more, but everyone always looks at me crazy when I saw that, so maybe I'll have one more and then we'll decide exactly how many! I think I would want a boy somewhere in the mix."
