Megan Fox displayed a very different look yesterday as she stepped out with husband Brian Austin Green.

The newlywed decided to forgo her usual make-up, revealing a completely make-up free face instead.

Perhaps the actress is just relaxing in her new official role as wife and stepmother.

The Transformers star chose the au naturale look to pick up eight-year-old stepson Kassius from his karate class.

Unfortunately her risque outfit wasn't exactly appropriate for the task.

While Brian kept it simple in dark trousers and a T-shirt, Megan opted for a much more risque look.

In a skimpy tank tip that revealed her bra, she didn't quite look the typical mother collecting a nine year old from school.

It's a look more suited to her sexy Armani billboard ad, currently positioned on Los Angeles' famed Sunset Strip in West Hollywood.

The 24-year-old actress looks stunning wearing a lacy bra and knickers in the black and white advertisement.

Football star, Ronaldo, 25, is clad in some brief Y-front underpants and his muscular, defined and perfectly formed body is on full display.

These are the second set of ultra sexy ads featuring Fox and Ronaldo that have been released by the Italian design house.

In the last campaign, released at the beginning of September, Megan is pictured answering a hotel door to a room service waiter wearing only her Armani underwear and a robe.

Meanwhile Ronaldo gives a housekeeping employee more than she bargains for when he wanders into his suite wearing only some tight-fitting briefs.

He proceeds to slowly put on a pair of Armani jeans, but not before a few gratuitous close ups of his rippling six pack and backside.

Ronaldo and Fox were signed as the new faces (and bodies) of Armani back in January.
