Megan Fox's Style Evolution: From Young Starlet To Sultry Stepmom (PHOTOS)

While Megan Fox hasn't always been recognized for stellar on-screen acting, whether it was in the "Transformers" films or the horror movie "Jennifer's Body," what the Tennessean girl does know how to do well is pose, pout and perfect that sultry stare that's made her one of Hollywood's most sought-after sex symbols. And though she may be lusted after by millions, Fox has remained faithful to her husband of two years, "90210" actor Brian Austin Green (with whom she may have a child very soon).

Even with the edgy attitude and numerous tattoos, Fox remains a down-to-earth girl at heart and her laid-back style is a true reflection of that. She's worn thigh-high slits and body-con looks on the red carpet, but prefers jeans and tanks when she's off-duty and playing step mom to Green's 10-year-old son Kassius. From teen queen to grown-up star, we're celebrating Fox's 26th birthday on May 16th with a look back at her style through the years.
