Jennie Garth is embracing confidence – at any age.

The 53-year-old Hollywood actress stripped down for her very first underwear campaign and said she's never felt better.

"I never thought I’d be doing my first underwear shoot at 53… but here we are!" Garth shared on Instagram. "And I’ve never felt more confident, or comfortable in my skin."

The "Beverly Hills, 90210" star showed off her toned physique in a series of lingerie photos, posted on the company ThirdLove's social media page. She was all smiles as she modeled a light blue bra and matching bottoms.

Garth continued to show off her fit physique in a beige two-piece set and blue cover-up.

In her last photo, Garth was seen putting on jeans, while she wore a beige bra, styled with a yellow button-up shirt.

Garth introduced fans to ThirdLove’s collection, which includes a line of bras and underwear created with "natural volcanic minerals" designed to regulate body temperature.

"These styles are my go-to from hot flashes to long travel days and everything in between," Garth's caption read.

She thanked the company for the collaboration for "helping me feel strong, sexy, and supported—exactly as I am."

Garth's sultry lingerie campaign comes after she opened up about her health challenges last year.
