"She's a very interesting one. She goes through all the gamut, but she is not the type of girl that likes a fuss. She toys with the idea of painting her nails or dyeing her hair even, and then she's like, 'Nope, I don't want to sit through it.' " Christina Aguilera Instagram " RELATED GALLERY: Buddy! Aspen! Hal!

Aguilera — who also shares son Max Liron, 13, with ex Jordan Bratman — said she took time this summer to head to the East Coast to visit both her hometown of Staten Island, New York, and Rutler's in New Jersey. "I'm here with the family. It was important for me to have everybody come together after being locked down for so long," she said. "I wanted the kids to see their cousins, so we're like on this little vacay in our hometowns, seeing family, but also working through it."
