Rebecca Romijn and husband Jerry O'Connell definitely want more kids, but in an exclusive interview with RadarOnline.com, Jerry jokingly warned  he didn't think they'd "ever catch-up to Octo-Mom!"

We caught up with the couple at the Children Raising Children fundraiser in Pacific Palisades Sunday. "Every child needs a loving home," O'Connell says. "I'm glad were able to be here and help support."
