Shania Twain is 'sex-crazed': Her husband is complaining because she's wearing him out!

Shania Twain is feeling as youthful and energetic as ever at 59, but insiders claim that her 54-year-old husband, Frederic Thiebaud, is having a hard time keeping up with the singer's newfound vitality - particularly when it comes to her high libido.

The country-pop icon wowed fans on the red carpet recently, looking stunning in a fitted dress that showcased her rejuvenated spirit.

A source told RadarOnline, "Shania's getting rave reviews everywhere. She looks fantastic, and her energy levels are through the roof, which is such a massive relief after grappling with her health for nearly 20 years."

Twain's health challenges date back to 2003, when Lyme disease derailed her career. The illness left her suffering from fatigue, dizzy spells, and vocal cord damage, forcing her to spend 15 years regaining her voice.

Shania's new lease on life

Now, after overcoming those challenges, Twain feels like she's been given a second chance, with her energy fully restored. Along with her current Vegas residency, she's enjoying life more than ever.

"She battled back and feels like she has a new lease on life," a source revealed. Her husband of 13 years is "thrilled" to see her "going full steam ahead again."

However, the same source also revealed that Twain's revived energy has extended into the bedroom.

"Her libido is sky-high, and Frederic has been complaining to people that she's wearing him out!"

The insider continued, "He adores her and thinks she's the most beautiful woman in the world, but he doesn't have the stamina of a twenty-something, so he's worried about keeping her satisfied."

Although Twain's representative dismissed the rumors about her husband's struggles, it's clear that Twain is embracing life with enthusiasm, and Thi?baud remains supportive, even if he finds it challenging to keep up.
