Everybody’s got one in there circle of friends. Someone with a mom that’s so hot, she routinely gets mistaken for her son’s girlfriend.

Liu Yelin is one such cougar. The 49-year-old Chinese mother of a 22-year-old son, who says she rarely wears makeup, attributes her youthful appearance to her status as a fitness junkie with an extreme passion for swimming.

“People are often shocked to find out I’m almost 50,” Liu told Daily Mail. “Whenever I went shopping and told people my real age, I often got mobbed by strangers who wanted to find out my secrets.”

To give you an idea of how serious she is about fitness and swimming, Liu swam the 7.45 miles between the shores of Penang, Malaysia and the Strait of Malacca last year in just 4 hours.

“I swim in the lake and do weight training every day,” she said. “My favourite thing is swimming outdoors in winter. When everyone was wearing down jackets, I had to strip down to my bikini and dive into freezing water. It’s a test for my will and perseverance. I often had to force myself to do it.”

And her wrinkle-free complexion has not only attracted a social media following of 75,000, dozens of directors have lobbied to get her on their programs. Take a look at her some of her pics and you’ll quickly understand why.
