Say this for Victoria Beckham: The woman knows her audience. How else to explain her pimping out hunky husband David to hawk her new line of designer sunglasses?

On Oct. 20, the Posh One tweeted a close-up photo of the 35-year-old soccer stud wearing a pair of her Classic Aviators in the Sky hue, reports the Daily Mail.

The stubbly L.A. Galaxy star, clad in a knit hat and white tee, is seen flashing his tattooed biceps and an ear-to-ear grin as he models for his missus. Beneath his pic: the note "X vb X."

The sunglasses are the same style that Victoria, 36, posted to Twitter earlier in the week, along with the message, "Just received new #victoriabeckham samples. Colours are beautiful."

A savvy businesswoman, Mrs. B no doubt saved herself a pretty penny by having her sporty spouse -- who commands millions as a product pitchman -- wear her shades for free.

The Spice Girl -- whose son Romeo plans to launch a collection of sunglasses for kids -- has been plugging her new eyewear collection like crazy, even urging Twitter fans to reserve their pairs now, lest they be out of luck, according to the Daily Mail.

"Get on the waiting list at Harvey Nicks!" she wrote. "New #victoriaBeckham glasses drop at the end of Nov!"

Just don't expect to get your own David with every pair.
