Los Angeles, April 26 (AZINS) Singer Christina Aguilera says she is a huge fan of actress Hayden Panettiere because she is like "a little feisty pit bull."

The "Your body" hitmaker says she is a huge fan of the "Nashville" actress and formed a close bond with her while guest-starring on three episodes of the TV series.

"I like her a lot because she's one of those little feisty pit bulls, like, small packages, big bites. I love that. I was such a fan of hers," Aguilera told eonline.com.

The 34-year-old singer, who has six-month-old daughter Summer Rain with fiancé Matthew Rutler and seven-year-old son Max with ex-husband Jordan Bratman, also couldn't resist asking the 25-year-old actress about her Ukrainian boxer fiance Wladimir Klitschko.

She said: "I was like, 'What's it like being married to this big, huge boxer, what's that like?' because I'm a huge boxing fan."

Asked if she would consider returning to the country music drama in the future, she added: "For sure. I had such a great time. They were so welcoming and so sweet to me. It was a great experience that I got to leave with. A lot of love in the air. Everyone was super, super fun."
