Speaking in a new TV interview, the singer, who is married to 67-year-old American music executive Tommy Mottola, revealed she keeps her looks in check thanks to nightly multiple orgasms.
Singer Thalia, who has also penned books, credited sexologist Nancy Alvarez for the advice.
She explained: 'I was working on a radio program where Nancy gave advice and well, she gave me some marvelous tips too.'
This is not the first time that Thalia, who is dubbed the Queen of Latin Pop and worth an estimated £35million, has spoken candidly about her sex life.
Thalia - real name Ariadna Thalia Sodi Miranda - said: 'My hobby is sex. Luckily for me, my husband also has the same hobby.'
Thalia is blissfully in love with Mottola, the former head of Sony Music Entertainment who discovered and guided the careers of Beyoncé, Bruce Springsteen and Shakira, and was once married to Mariah Carey.
The couple married in 2000 and have two children, Sabrina and Matteo.
Thalia has sold close to 50 million records worldwide. Her 2013 Latin pop-bachata song Te Perdiste Mi Amor, which also featured American singer Prince Royce, proved her biggest hit to date selling almost 1 million copies.
