The rumours started after some began to wonder how Humphries, 26, a New Jersey Nets player with a yearly salary of just 3.2 million dollars, could afford a 20.5-carat ring worth a reported 2 million dollars, the New York Daily News reported.
Other outlets reported that Kardashian actually bought the jewel for herself years ago, and MediaTakeOut.com dug up an old post of its own from 2008, featuring the reality star wearing a giant diamond ring on her right hand.
A side-by-side comparison of the ring and the one Kardashian recently sported in People magazine, which announced her engagement to Humphries, shows an uncanny resemblance between the two sparklers.
Both appear to feature an emerald-cut centre stone with trapezoid-cut stones on each side, set in what appears to be a platinum band. (ANI)
