Susan Anton, one of the biggest models of the '70s, is just as gorgeous at 66

Sexy Susan!

Susan Anton, now 66, became a household name in the '70s as the sexy spokesperson for Muriel Cigars. It's safe to say that her beautiful features -- voluminous blonde locks, a perfect physique and a gorgeous face -- turned her into one of the hottest women of her generation. If you walked into the room of any male teenager, chances are you'd see a poster of Susan on the wall.

While her stint at Muriel Cigars catapulted her into the public spotlight, Anton's Hollywood career following her big break was mediocre at best.

The star scored a number of TV roles, including a brief stint on Merv Griffin's TV show, but nothing ever compared to her role as the Muriel Cigar's spokesperson. In 1978, ABC gave her and country singer Mel Tillis a summertime variety series, "Mel and Susan Together," but it was cancelled after four weeks. Despite the failure, she was still chosen as one of Time Magazine's "Most Promising Faces of 1979."

Susan also didn't have much luck in the music industry, though one duet with country singer Fred Knoblock, titled "Killin' Time," made Top 10 in the country charts back in 1980.

In the early '90s, she had several stints on major TV shows, including "Baywatch" and "The Larry Sanders Show." Her most recent role was in TV film "Sharknado: The 4th Awakens" in 2016.

However, Susan made headlines for much more than her sexy posters or her acting career -- the golden girl had quite the love life. For a hot minute in the early '80s, Susan was involved in a romantic relationship with "Rocky" actor Sylvester Stallone. The only problem? He was married at the time. Their relationship fizzled out and they parted ways.

Soon after, Anton made headlines again for her relationship with British film star Dudley Moore due to their drastic height difference (He was '5"2 and she was '5"11). Anton then married her second husband, TV actor Jeff Lester, in 1992. She was previously married to Jack Stein, but divorced after 5 years of marriage in 1980.

The once-famous model currently resides in Las Vegas, but she has remained out of the spotlight. While we've seen less of Susan in recent years, she's still as gorgeous as she was back in the '70s and '80s. Anton flaunted her ageless appearance at an event in Las Vegas just last year -- and we're totally blown away by her youthful appearance. What's her secret?!
