Megan Fox Bares Her Side Boob Tattoo in a Plunging Tie-Dye Bra

Megan Fox stars in "Expendables 4" as Gina, opposite Jason Statham as Lee Christmas. The newly released trailer shows the 37-year-old mom of three embracing quite a nostalgic trend from the early aughts with her plunging tie-dye sports bra, a gray design that completes her workout set in one of the first scenes. Teamed with a pair of black high-waisted leggings and sneakers, Fox's toned abs are on full display — as is her side tattoo when Statham pins her to the ground during an impromptu wrestling match. Fox's long, dark hair is parted at the center and woven into a messy, post-exercise braid, while her makeup appears untouched with peach blush and a glossy pink lip. Though the athleisure look is fit for boxing class, it's also reminiscent of many an off-duty moment from the 2000s, when a spiral-splashed bra like this one could have made for the foundation of a Juicy Couture velour tracksuit. Fox sets down her leather tote bag as she enters the room — the final accessory to cap off her outfit.

While "Expendables 4" doesn't come out until Sept. 22, Fox has been sharing plenty from her summer wardrobe recently, including a tiny black thongkini from Indah with a cutout, textured bandeau top. She has also been spotted out for date night coordinating with Machine Gun Kelly, rocking everything from a charcoal gray corset minidress with thigh-high boots to a sheer white tank top and chain-embellished pants. Fox celebrated her 2023 Sports Illustrated Swimsuit Issue cover in both a plunging knit maxi with a ruffled neckline and a revealing LaQuan Smith naked dress, accessorized with an intricate diamond ring from Le Vian and pink chrome nails. While she and MGK spawned months of breakup rumors, the couple seem to be on good terms at the moment.
