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.
