High School Musical’s Ashley Tisdale pays a visit to a very deserving family on this Sunday’s episode of Extreme Makeover: Home Edition. The 24-year-old starllet is taking part in the show’s “Get On The Bus Program,” in which celebrities volunteer to take part in the home building process.

Ashley traveled to Green County, Missouri to help the Hampton Family move out of a tiny 800 square foot cottage, where the clan of eight had been living together since the family took in four nieces and nephews who were in danger of ending up in foster care.

“When I saw the family and the reaction to the house I just, like, started tearing up,” Ashley explains. “It’s like this really great deserving family and then also you see like all these volunteers and their family members and their friends just all getting together helping them. It’s just such a great feeling to be part of that.”

Ashley recently moved into her own new home — built by her dad — and the actress was very hands-on in putting together the Hamptons estate. “I helped out a lot around the house. I did the floors in the entryway. I did a little of the designing of Hannah’s room, which is the little girl who was super excited to meet me. I also worked a little bit on the chicken coop in the back and the barn house as well.”

Ashley Tisdale stops by Extreme Makeover: Home Edition this Sunday night, Oct. 4 @ 8PM on ABC.
