The `Because of You` hitmaker admits her home has become like a "rescue ranch" as she is so willing to take in sick and abandoned creatures.
She said: "It`s like a rescue ranch now. We have 30 dogs, 14 horses. We still only have three ponies and four minis, but we have goats now, two pigs we rescued called Miss Daisy and Boss Hog, I gave those to my brother."
While Kelly loves getting new animals, she insists there are some creatures she wouldn`t take in because they are just too big.
She explained: "There are elephant sanctuaries about one mile from where we are - which in Texas isn`t that far because we`re all spread out - and people have asked would I ever take in something that big. And I`m like, `No.` Leave that to the elephant sanctuary. I think there`s a tiger sanctuary in Texas too. We would never have tigers."
Despite being surrounded by animals, the 29-year-old star is still happy to eat meat, though she insists she wouldn`t sacrifice any of her pets for dinner.
She told NME magazine: "I eat pork, don`t get me wrong but I`m not going to bake my own! I can`t do this. I can`t maim them then eat them, that`s wrong."
