Mad Men star January Jones stunned fans on Tuesday when she shared a series of sizzling swimsuit photos that showcased her enviable figure.
The 48-year-old snapped the photos in the bathroom of her home in Los Angeles, and looked better than ever in the various ensembles.
The first photo saw January in a white and green bikini top underneath a sheer white lacy shirt, with her blonde locks falling down to her shoulders.
The next snap featured the actress with a bright smile on her face while dressed in a black bikini with a white trim, as she showcased her incredible physique.

“Gorgeousness,” one fan wrote, while another added: “Beautiful as always.” A third declared that she was “smokin’ hot,” while another chimed in: “Still the most beautiful thing ever.”
January’s stance on working out
January explained to Shape how her relationship with exercise had changed over the years, after growing up with a fitness trainer for a father.
“My dad was a trainer, so in my 20s and 30s, I didn’t work out, because he was always pushing my sisters, my mom, and me to exercise. We would rebel and not do it,” she told the publication.

Even when she joined the cast of X-Men: First Class as Emma Frost, January would lie about working out with the trainers the studio provided her, and instead would watch TV in her hotel room and have “full tea service”.

She began to take barre classes to help with her posture, then moved on to Pilates. “I’ve gained weight because I’ve put on muscle. I’ve gone up a size in clothes, but I feel like I look better naked,” she shared. The Golden Globe nominee added that she does not follow a diet and never deprives herself of eating what she wants.
Perimenopause struggles

“I haven’t been officially diagnosed, but I think I have the perimenopause,” she told her fans, adding that her usually “light and fun” personality had switched to one with “a lot of rage”. Perimenopause is the transition phase before menopause, when hormones are changing and menstruation becomes irregular.
