There is a huge chance that Selena Gomez is singing about her sexual relations with on-and-off boyfriend Justin Bieber in her new song, "Do It."

Hollywood Life reported that the 22-year-old singer is "openly singing about wanting to have sex" with Bieber over and over again. The track leaked online on November 20, and based on the lyrics, Gomez seems to have no qualms revealing the details of her steamy and addictive sex life with the Canadian crooner -- that is, if the song is indeed about Bieber and their adventures in bed.

An insider told Hollywood Life that Gomez thinks Bieber, 20, is the ultimate lover for her.

"Selena always described her sex life with Justin as explosive - like fireworks. Justin told her that she was the ultimate lover, his princess soul mate. He always complimented her, saying she was his number one. No one compared to her (sexually). That's what ultimately always brought them back together. The sex was addictive, like a drug. She just had to write about it in 'Do It.' She said Justin loved the song. Obviously he knew it was about their sex life, and gave her two thumbs up after he listened to it for the first time," the source revealed to Hollywood Life.

The couple broke up (again) last October. Just recently, J-14 reported that Bieber unfollowed Gomez on Instagram, prompting rumors that he is indeed over the former Disney star. But according to another report from Hollywood Life, Bieber has been trying to win Gomez's heart back because for him, having sex with the singer/actress is "one of the best feelings in the world."

"Selena is the only girl he's ever slept with that he actually has real feelings for, so sex with her is on a different level. He's been with girls that have a lot more experience, who are way more wild, which is exciting, but in the end, it's still Selena he would pick over all them because he loves her," Hollywood Life's source revealed.

Bieber also wants to surprise and support his ex-girlfriend by making an appearance at the American Music Awards, where Gomez will be performing at on November 23. According to Hollywood Life's insider, "He feels like that's the only thing that will make him happy."

Read the full lyrics of "Do It" below, as published by Hollywood Life. It's pretty obvious that Gomez is singing about Bieber.

"DO It"

Sitting on a bed with just your t-shirt on

Turning up the volume to my favorite song

Boy I can't lie, what we did last night

It's caused me to reply the same on my mind

I show you what I like, if you show me what you like

If I had a choice, if I had my way

Boy you know we'd do it every single day

If I had a wish and if I had my way

Boy you know we'd do it every single day

Damn I wish I didn't feel so hypnotized

When I look at you baby it's justified

I take what I want, and give what I've got

To help with all the rules that keep us civilized

I show you what I like, if you show me what you like

I show you what I like, if you show me what you like

If I had a choice, if I had my way

Boy you know we'd do it every single day

If I had a wish and if I had my way

Boy you know we'd do it every single day

Nowhere I'd rather be than anywhere alone just me and you

Well be together for ever we'll ride

I want you more and more

If I had a choice, if I had my way

Boy you know we'd do it every single day

If I had a wish and if I had my way

Boy you know we'd do it every single day

I show you what I like, if you show me what you like

I show you what I like, if you show me what you like
