THEY'VE made millions singing some of the world's romantic songs - so it will come as no surprise pop stars know more than a thing or two about love.
Which means they know how to hit the right notes on stage - and in the bedroom, too.
From 'listening to their own music' while making love and revealing intimate details about threesomes, to sharing their own tips and tricks, here we take a closer look at some of the sauciest sex secrets of the world's biggest singing sensations...
Cheryl's little breaths
For the most part, Girls Aloud singer Cheryl keeps her private life very much out of the spotlight, but that's not to say she hasn't let slip an intimate detail or two over the years.
When married to first husband Ashley Cole, Cheryl revealed in an interview with the Mirror: "We tackle each other in the bedroom and he loves me massaging his feet.

"I think more men prefer to hear little breaths rather than big loud screams. Otherwise you sound like a porn film."
Cheryl went on to admit that sex with someone she loves is more important to her than “all the money in the world" adding: "Sex makes me happy, money doesn’t."
Madonna's fake sex acts
Like A Virgin singer Madonna, 65, isn't afraid to shock, and in her 1990 documentary she even pretended to perform an lewd sex act with a bottle and talked openly about her wild bedroom antics.
Then, in 2021 MTV documentary Madame X she admitted she liked men to "f*** me then get out" and bragged she is "known" for self-pleasuring on stage.
Madonna first pretended to do it on a bed during her 1990 Blond Ambition tour, and it almost led to her being arrested during a show in Canada.
While chatting to US comedian Dave Chappelle, she said: "I always masturbate, I’m known for it.
"You’re known for smoking on stage, I’m known for masturbating on stage."
Mariah Carey's musical tones
She has one of the world's most beautiful voices, so it would hardly be surprising if Mariah Carey's now ex-husband Nick Cannon's revelation that they listened to her songs while intimate were true.
Speaking to Amber Rose on her show in 2016, he said: "I've answered this question while I was married - mistake!
"She didn't like the fact that I told the world that we have sex to her music, but it was true!
I want my girlfriend to try dirty talk but she won't do it
"Can you imagine having sex with Mariah Carey while Mariah Carey is playing in the back? Sorry, Mariah. I said I wasn't going to say that again."
Mariah once said: "I’ve only been with five people in my life, so I’m kind of a prude, honestly, compared to most others in the field."
Robbie Williams' many notches
He's happily married and settled down with wife Ayda Field now, but before Robbie Williams had many high-profile romances over the years.
The 49-year-old was lucky enough to date a whole host of famous women including Melanie C, Geri Horner and Nicole Appleton.
Both Robbie and Ayda have always been open about their sex life since they wed in 2010, or lack of it - with the Rock DJ singer saying: "Everyone knows there is no sex after marriage. That’s just the way it is."
However, before that he openly admitted he was "addicted to having sex with strangers" and reckons he's bedded more than 110 women.
Liam Payne's sexy lyrics
Former One Direction star Liam Payne, 30, likes sex so much - he can't help but sing about it, apparently.
Speaking to Gaz Drinkwater on Total Access in 2018, Liam explained: "I like sex.
"So what better way than to musically express myself as a young man growing up.
"I’m into it. I like it. It’s good."
His solo hit single Bedroom Floor, for example, referenced his bedroom antics - rumoured to be referring to ex Cheryl - with the lyrics: "You said it was over, but your clothes say different on my bedroom floor. We always on and off until you’re on me."
A year later, Liam was rumoured to be enjoying "mind-blowing" romps with supermodel Naomi Campbell.
Justin Bieber's connective sex
They're one of the world's sexiest couples, so no wonder Hailey and Justin Bieber have serious chemistry.
The pair wed in 2018, and Hailey got extremely candid about their sex life when speaking on podcast Call Her Daddy, hosted by Alex Cooper.
When asked about their favourite sex positions, Hailey said: "It's not like I'm like 'I strictly like this one thing' and he strictly likes another thing.
"It's always different... I really like doggy-style."
When asked about what turns Justin on, she replied: "The connection point is very important to him.
"We could literally just be laying down talking before and just like having a really fun conversation and that is really important for him."
