*Last week, Jennifer Hudson and her fiancé David Otunga threw a wrestling-themed birthday party to celebrate their son’s first birthday – and even dressed the child like his daddy – who just happens to be a wrestler.

“He had a wrestling ring built out of a jumping castle that had ropes on it saying ‘Raw’ on one side and ‘Smackdown’ on the other. It was huge. Adults were in it!,” Otunga told HollywoodLife.com. “I got him an exact replica costume that I have. I had my seamstress make the same trunks I have, including the Nexus arm band, the hoodie and jeans.”

Hudson, 28, and Otunga, 30, say they’d love to have a little brother or sister for the birthday boy.

“David (Jr.) is so great, you can’t help but look forward to the next one,” the proud papa tells InTouch Weekly. “I want to fully enjoy him right now and let him have his time to shine as the only child, but we don’t want to wait too long.”

David also spoke of how David Jr. has made his love for the “Dreamgirls” star even stronger.

“I feel like I couldn’t love this person any more, and then I see her with our child, and it’s like, ‘Wow.’ It’s like nothing you can imagine.”
