Kelly Clarkson performs during the GRAMMY Celebration Concert Tour held at The House of Blues. Boston, USA - 04.05.09

The pop star has 10 horses and 10 dogs at her ranch in Texas - and she's just brought a rescue puss home.

"They were about to put her to sleep... I vowed I'd never get one because I have a lot of antiques and all my animals are outside, but I couldn't (say no)."

But the new pet is a heavyweight problem for the singer: "She's over 20 pounds and she loves sleeping on my chest."
