Gisele Bündchen is already the world's richest model, but her wealth is about to hit new heights. As her lingerie line goes global, Gisele is set to become the world's first billionaire model.

The Gisele Bündchen Brazilian Intimates range was launched last May and has already proved popular in Latin America, Portugal, Japan and Israel. Now, further expansion is expected.

With her various product endorsements and business ventures, Gisel earned a total of $45 million USD last year. She's now on track to become the first billionaire supermodel.

Model Bar Refaeli, 26, is said to be following in Gisele's footsteps and is also preparing to launch her own collection of underwear next month.

The negative press continues for the Kardashian klan, who after being accused of orchestrating Kim's "fake" marriage to Kris Humphries, are now linked to sweatshop labor. Star Magazine claims that several items sold under the K-Dash by Kardashian label, the Kris Jenner Kollection and Kim Kardashian's ShoeDazzle line are made in regions of China where factory workers endure horrific working conditions.

Human rights investigators went undercover at several factories linked to Kardashian products. While the Kardashians raked in $65 million last year, workers at the factories making their products are paid as little as $1 per hour. Some of the workers were also found to be as young as 16-years-old.

So far, the Kardashians have not issued an official response to the report that their products are made in sweatshops.

Abercrombie & Fitch is none too pleased that the cast of Jersey Shore actually likes and wears their clothes.

Specifically, Mike "The Situation" Sorrentino is a fan of the brand and has been seen wearing it.

Abercrombie added:

"We understand that the show is for entertainment purposes, but believe this association is contrary to the aspirational nature of our brand, and may be distressing to many of our fans."

"All good things have to come to an end. I will always love Victoria's Secret. It has been an absolutely amazing time."

With Klum now out of the picture, the "Head Angel" slot is open. The Daily Mail reports that Alessandria Ambrosio and Adriana Lima are in the running to take over, as Miranda Kerr and Doutzen Kroes are both pregnant. Although less likely, Chanel Iman, Erin Heatherton, Rosie Huntington-Whitely and Candice Swanpoel still have a shot at it.

While walking the runway is now out of the picture for the near future, Klum will be keeping herself busy by hosting "Project Runway" and working on her new activewear collection for New Balance.
