When it comes to inciting jaw-dropping reactions from a red-carpet appearance, nobody does it better than Megan Fox.

The 28-year-old actress hones her look in a fresh and modern way — and she’s bound to set off more flashbulbs as she kicks off her promotion tour for Friday’s “Teenage Mutant Ninja Turtles.”

Here, take a look back at her most head-turning looks.

Fox traveled to Mexico City for the premiere of “Teenage Mutant Ninja Turtles” on July 30 in a cream Zuhair Murad mini emblazoned with green and blue beading.

With a thigh-high slit and peek-a-boo side cutout, Fox served up ample rounds of heart palpitations in a Roberto Cavalli stunner she wore to the “Transformers: Revenge of the Fallen” photo call in 2009.

Three years before Angelina Jolie made it famous, Fox leg-bombed the red carpet in a satin purple Donna Karan gown she wore to a 2009 “Transformers: Revenge of the Fallen” premiere.

For the 2009 MTV Movie Awards, the blue-eyed beauty swapped her trademark long gowns for an arresting brocade cocktail dress by Dolce & Gabbana.

Fox slipped into a chiffon Valentino dress adorned with lace and ruffle detail for the 2009 “Jennifer’s Body” premiere at the Toronto International Film Festival.

The “Transformers” alum wore a thigh-high Giorgio Armani Privé gown — complete with low-plunging neckline — to the “Jonah Hex” premiere in 2010.

Fox strutted down the 2013 Golden Globes red carpet in a lace nude gown designed by Dolce & Gabbana — with handsome hubby Brian Austin Green on her arm as the ultimate accessory.
