“Mario is crazy about kids,�? says the friend. “He has the best time playing with his nieces and nephews and would love more than anything to raise some children of his own.�?

There’s just one problem: Karina, who fell for Mario when the two danced together in the hit ABC reality show “Dancing with the Stars,�? won’t make time for changing diapers unless he becomes Mrs. Lopez!

“Karina is wild about Mario and would love nothing more than to start a family with him, but she also firmly believes that it’s important to be married before she gets pregnant,�? adds their friend. “She’s not going to give in on this.�?

Continues the friend, “unfortunately for Mario, once Karina has set her mind to something, she doesn’t budge.�? Karina will have to stand firm – and maybe for some time! Mario is “scared of commitment,�? says their friend. “He is completely wild about Karina, but the thought of settling down for good puts him in a state of panic.�?
