KELLY TURNS TIGHTWAD!

PENNY-PINCHING Kelly Clarkson is tightening the purse strings by listing two of her three mega-mansions for sale — and sources predict other big changes are coming!

“Kelly is being very sensible about her finances and making adjustments that reflect where the world is today,” spills an insider.

“She’s worked her butt off to get where she is, but it’s common knowledge salaries on The Voice are likely to be cut soon, and she wants to be safe now, not sorry later on!”
