It looks like Glamour is making good on its word -- made last year -- to feature women of diverse sizes in the magazine.

According to WWD, the June cover of Glamour will star a delectable threesome of Victoria's Secret stunner Alessandra Ambrosio, Sports Illustrated Swimsuit Edition cover girl Brooklyn Decker and "plus-size" model Crystal Renn, whose career has been soaring of late.

Renn recently appeared in back-to-back issues of V Magazine, including the provocative "Size Issue," which was inclusive of some super-curvy women including performer Miss Dirty Martini, shot by Karl Lagerfeld.

Perfect for a summer-themed issue, WWD reports that the three luscious ladies were photographed in St. Barths by Matthias Vriens-McGrath this past weekend. And, judging by pictures posted on Ambrosio's Twitter, it looks like bathing suits were involved, as was star hairstylist Ted Gibson.

The June cover not only sets a benchmark for featuring women of varying body types, but it also marks a return of using models (instead of celebrities). Ironically, the last time a model was featured (in May 2006), it was Ambrosio.

Renn's relationship with Glamour started with a fashion story in May 2009, then continued last fall when she appeared naked with a bevy of other "plus-sized" models in the November issue, also shot by Vriens-McGrath.

Most recently Renn ditched the runway for a front row seat at the shows in New York, working as a guest blogger for Glamour.com. Then she returned to the catwalk for the London and Milan shows, strutting her stuff for Mark Fast and Elena Miro, respectively.

When StyleList spoke with Renn last month, the model had some very exciting upcoming projects that she had to stay mum about. We're guessing this Glamour cover shoot might have been one of them.

Can a major ad campaign be far behind? We think not!
