"I'd love to have more children but I've said to myself that 40 is my cut-off point to have another baby," Hunter, 36, told the new issue of Reveal magazine.
Hunter's eight-year marriage to rocker Rod Stewart produced two Renee, 13 and Liam, 11.
Hunter said despite the breakup of her marriage and several well-publicized failed relationships, she's still optimistic about love, the Mirror reported Tuesday.
"I still haven't found the man of my dreams but I hope he's still out there," she said.
