Another one bites the dust!

Word on the curb is that Jennifer Hudson and her fiance of 3 years, David “Punk” Otunga have officially called it quits.

After a three-year engagement, Jennifer Hudson has abandoned plans to walk down the aisle.

The American Idol alum, 30, and WWE star David Otunga – who have a 2-year-old son, David jr. – are on the outs, clashing over Jennifer’s career obsession, commitment issues and reluctance to have more children.

“They were going to tie the knot in August in Jennifer’s hometown of Chicago… but it’s not going to happen,” an insider reveals.

Many feel that it was Jennifer’s dramatic weight loss that caused the split, but there were also rumors that J-Hud’s finance/baby daddy had refused to sign a prenuptial agreement after they had already set a wedding date.

The pair has rarely been seen together these past few months, so are you really surprised about this break-up news?
