Gotta camouflage that 2nd pregnancy, also for what it's worth the daily mail reports that that necklace cost $350,000 and it's supposedly the logo from one of her makeup line products. However I don't think any celebrity pays full retail for any of these diamond pieces that they get custom made. Correction I don't think that the Kardashian-Jenner's and their men of the hour pay full retail.
But Travis did go on tour and I know artist when they go on tours at all of that money goes directly to them so maybe he's banked quite a bit of money because didn't this past Christmas he purchased his mother a range Rover and his dad Porsche? those are $100,000 plus cars
