Not yet officially welcoming Danielle Deleasa into the family, Denise Jonas has sung praise for her soon-to-be daughter-in-law. To People she gushes, the former hairdresser "is the right girl" for her oldest son Kevin Jonas. She, moreover, reveals how she often teases Kevin by saying "You're marrying your mother - but she is just thinner and prettier."

And it appears that Denise isn't the only person in the Jonas family who loves Danielle. Frankie Jonas, the youngest of the four Jonas boys "really loves her and is proud of her," says Denise. "He already acts like a little brother [to her]."

"My role has really changed," the 43-year-old mother says of sons Kevin, Joe Jonas, and Nick Jonas already obtaining their driver's licenses and diplomas. However, "I'm always their mom" she goes on emphasizing her role in the family now that Kevin is about to leave the home they share to live with his future bride Danielle. "Everything I did when [my sons] were younger is really paying off now," she concludes.

This isn't the first time that Denise Jonas opens up about Danielle Deleasa. Recently, she told Parade that Danielle and Kevin have chosen a wedding date, but she didn't mention when.
