Playing the part of sultry seductress is all in a day's work for Megan Fox.

The 24-year-old actress is making her debut as the new face of Giorgio Armani Beauty, with a just-released video spot that combines a hypnotic beat with equally mesmerizing close-up shots of the bombshell.

Transforming from dewy and neutral girl-next-door to full-on smoky eyed glamazon with hot red lips to match, Fox shows that she can pull off a variety of the brand's makeup looks.

We hear that famed makeup artist Linda Cantello wielded the brush for the ad campaign, while Craig McDean photographed and Mikael Jansson directed.

Armani says that he chose Fox as the new face of his beauty empire because, "she embodies the spirit of the women of today: free, confident and seductive. Her beautiful features reveal femininity, sensuality and strength."

And we're more than just a little jealous of the freebies we imagine Fox is scoring as the brand's new ambassador.

Known best for its luminous foundations and moisture-drenched lip colors with intense pigment pay off, Giorgio Armani Beauty is also known for its equally luxurious price tag, with the former retailing for nearly $60, and the latter for $27-$30 a tube.

Maybe Santa will surprise us. Until then, we're going to get pretty with this free beauty tip.
