Jennifer Aniston Continues to Look Perfect in Latest Smartwater Campaign Photos—Check Them Out!

Actress has repped the brand for several years

Two words: hair goals.

Jennifer Aniston's enviable mane is up front and center in her latest ads for the Smartwater #upupup campaign—not that we'd expect anything short of a perfect 'do on the A-lister.

The 46-year-old stunner filmed the ads in Los Angeles in March of this year with famed fashion photographer Ruven Afanador.

Aniston brought along her trusty sidekick—and longtime hair stylist—Chris McMillan for the photo shoot and appeared to have a blast while on the set based on the photos!

And when she's not busy being snapped on glamorous sets, Aniston is hard at work on other projects like, drumroll, a cookbook!

Aniston told Yahoo! Beauty that she's "working on" the forthcoming book at the moment and added: "I would like to do a lifestyle thing, for people who struggle with dieting. I could just make anything for a diet taste delicious. I can mix certain things together that are all very healthy, but you don't feel like you're depriving yourself in any way."

But with all her time in the kitchen whipping up delicious food, what does the former Friends darling do to make sure she stays in such great shape?

"Lately, because of my injury, I've only been able to do Barre method," she shared. "Boy, I forgot how much that really hurts and kicks your butt."

In a good way, clearly!
