Jennifer Lopez Keeps Loaner Diamonds

It's gotta be rough being famous. You're given thousands of dollars worth of loaner jewels for public appearances, premieres and parties - and all you have to do is look fabulous. Oh. And return them when you're done.

But some celebs apparently mistake the word 'loan' for 'give', which is exactly what the New York Post reports Jennifer Lopez did to jewelry magnate Robert Mouawad.

Apparently the mega mom borrowed $50,000 worth of diamonds from Mouawad to wear to the launch of Andrea Lieberman’s fashion line, ALC, at Barneys in Beverly Hills but later decided to keep the loaner diamonds to add to her private collection.

“We received a call from [her manager] Benny Medina, informing us that Jennifer was going to keep the jewelry,” an insider blabbed to the NY Post’s Page Six. “As far as Mr. Mouawad is concerned, Jennifer can have whatever she wants, but a premature demand seemed presumptuous.”

Medina later countered their claim by insisting the jewels were a part of the deal to appear at the function.

"There was no demand whatsoever. There was an offer. It was very clear," he said.

"She was the only celebrity whose name was on the invite. She would have done it for nothing. But this was how it was presented. It was quite a generous offer," he added.

What's the lesson here? J-Lo's love might not cost 'a thing', but her personal appearances certainly do.
