It’s been a year and a half since Jennifer Hudson’s fiancé, David Otunga, proposed to the singer with a 5.5-carat diamond sparkler from Neil Lane — and now, the parents of a bouncing baby boy are finally preparing to walk down the aisle! “The wedding is coming up. We have finalized most of the details and have some ideas about the honeymoon,” WWE NXT Rookie wrestler David tells In Touch. Jennifer, 28, has said she wants her special day “to be a full-on production,” and, of course, the couple’s son, 7-month-old David Jr., will be playing a big part in the nuptials. “I am getting him a custom-made tuxedo to match mine,” adds his proud father. “I can’t wait to see him in it, looking sharp like a little grown man!” Jennifer already has a Neil Lane ring, and she is “looking at Fred Leighton” for the wedding bands, an insider says.
