At 71, the actress hasn't looked better -- and that's not even the half of it. Somers invited ET into her luxe Malibu, California, home, where she dished to Keltie Knight about her new book, Two's Company: A Fifty-Year Romance With Lessons Learned in Love, Life & Business, and revealed how how she manages to do it all.
Check out the secrets to living life the Somers way.
1. Take Vitamins -- a Lot of Them.
"[I take] maybe 60 vitamins a day," Somers reveals while giving ET a tour of her kitchen. "You know, I'm in optimal health, so whatever it takes."
Among the actress' supplements are hydrochloric acid and digested enzymes, which she uses to help digest her food after going through radiation to treat breast cancer in 2000. One thing you won't see her taking, however, is aspirin.
"I don't take any drugs at all, nothing...I don't have a medicine cabinet. Neither of us do," she says of herself and husband Alan Hamel. "I don't say that I'm doing it the right way, but there are two ways to do this whole thing about health and aging. So I'm doing it that way."
2. Stay Away From Hard Alcohol, Unless It's Tequila.
"I never had a hard liquor drink until two years ago, because I come from a long line of alcoholics, and I was always afraid of it," Somers confesses. "I would drink a little wine, but I noticed wine was making me fat, [so] my kids said, 'Drink tequila.'"
"I said, 'I don't drink hard liquor.' [They said], 'Oh, try it,'" she recalls. "And I liked it."
3. Get Kinky.
"We sit here at night and listen to music and pretend we have our trio in the other room. And we talk and dance and it's nice. Life is good," Somers says of her and Hamel's nightly routine. "Whatever happens [happens]."
"We've never gotten to the couch, have we?" she asks her husband, before turning to a place she and Hamel definitely have gotten busy. "The bar, which we found sort of kinky."
4. Practice Yoga Every Other Day.
"I will do yoga till I die. I do it every other day," Somers says. "My yoga teacher comes and we do it here...And I use the Thighmaster religiously. So much so I was noticing that I worn off the thingy."
The blonde beauty has another secret weapon for her backside.
"The Buttmaster is incredible. You have to put this on and you can do the Buttmaster and the Thighmaster. It's very S&M-looking, but I mean, it really works," she shares. "It's like, 'Wow.' While I'm doing this, I'm working my core also."
5. Try Not to Spend Too Much Time Away From Your Significant Other.
"We are together 24/7, and we haven't spent one night apart in over 37 years," Hamel reveals. "It works for us."
Somers and Hamel have been together nearly 50 years, but that doesn't mean it was all sunshine and rainbows. In fact, the two considered breaking up just after moving in together in Santa Monica, and say the first 10 years of their relationship were the hardest.
"We were fighting... but we didn't know what we were fighting over," Somers says. "We were fighting over control and power and all those things, and children's feelings, and the great news is that we worked it out."
