Mariska Hargitay Debuts Fresh Bob Cut for Taylor Swift’s Wedding: ‘Cool Girl Hair’

Mariska Hargitay celebrated pal Taylor Swift’s star-studded wedding to Travis Kelce in style — with a flawless new ‘do to match.

Hargitay, 63, was among the famous faces present as Swift and Kelce, both 36, said “I do” inside New York City’s famed Madison Square Garden arena on Friday, July 3.

While Swift and Kelce each wore bespoke Christian Dior Haute Couture ensembles for the occasion, Hargitay and husband Peter Hermann twinned in black. The Law & Order: SVU star, for her part, donned a halter dress with a silver choker, both of which complemented her newly chopped bob.

“Fresh ✂️ for @therealmariskahargitay for the Taylor n Travis FUN,” Hargitay’s hairstylist, Chris McMillan, wrote via Instagram on Sunday, July 5, breaking down his glam process. “Prepped hair with @chrismcmillanhair glassy smooth blow-dry spray to keep humidity out (was 100 degrees that day) smooth strands and keep hair shiny and healthy.”

McMillan then applied his eponymous brand’s mousse to the actress’ mane “for lift around the face and crown.”

“Using hands to open up around the face and ad root lift rough dry strategy give hair direction and volume,” he explained. “Round brush blowout to create a more polished look and direction then @t3micro 1 1/4 [inch] flat iron to create the waves [and] flicks. My pro tip is using @chrismcmillanhair major hairspray as heat protection on dry hair to not only protect the strands but hold style for the long night of festivities.”

McMillan completed his styling with his balm for added texture to create a “lived-in, day-old hair same day edge.”

“Cool girl hair always for @therealmariskahargitay,” he gushed. “Bobs can be tricky. The key for this style is the side part, texture and BLUNT BOB.”

Hargitay has been friends with Swift for many years, appearing in the pop star’s 2014 “Bad Blood” music video alongside a slew of famous faces, including pals Selena Gomez, Hailee Steinfeld and Karlie Kloss. Swift, for her part, even famously named her first pet cat after Hargitay’s SVU heroine, Olivia Benson.

“When she named her cat, I had so much going on. I was out of town, and when things calmed down, I thought it warranted a real something [special],” Hargitay exclusively told Us Weekly in 2014, revealing she sent feline Olivia an engraved collar. “[Naming her cat after my character is] so sweet and too fabulous.”

Hargitay paid it forward nine years later, naming her then-new cat Karma after Swift’s Midnights song of the same name.
