[Intro: Charli XCX]
Lock it, lock it, lock-lock it
Lock it, lock it, unlock it
Lock it, lock it, lock-lock it
(Beautiful)

[Chorus 1: Charli XCX]
Rollercoaster ride in the fast lane
Got the roof down, kiss me hard in the rain
You got the candy-colored eyes, pink and gold chain
Million dollar babe, whip it out like I'm propane

[Verse 1: Charli XCX]
You're on my mind
I'm feelin' kinda nervous but I like it
Take my T-shirt off and do it right
You're on my mind
The feelin', like an astronaut
Watchin' the world all alone, just you and I (you and I)
(Beautiful)

[Chorus 2: Charli XCX]
Rollercoaster ride in the fast lane
Got the roof down, kiss me hard in the pourin' rain
Yeah, I can see it in your eyes, know you feel the same
Million dollar babe, trippin' on it like propane
(Beautiful)

[Post-Chorus: Charli XCX]
Lock it, lock it, lock-lock it
Lock it, lock it, unlock it

[Verse 2: Kim Petras]
Caught in a lip lock, when we pit stop
Cosmic kiss, tastes like cherry maraschino
Ride, passenger seat, tropical heat
Eyes so red, you could be my Valentino, yeah (Woo-ah!)
If you want my heart, then don't you drop it
(Want my heart, then don't you drop it)
I'm right here, right in your pocket
(I'm right here, right in your pocket)
Pull it, cock it, never stop it
(Never stop it)
If you want my love (my love!), try to unlock it

[Chorus 2: Charli XCX]
Rollercoaster ride in the fast lane
Got the roof down, kiss me hard in the pourin' rain
Yeah, I can see it in your eyes, know you feel the same
Million dollar babe, trippin' on it like propane
(Beautiful)

[Verse 3: Jay Park]
Unlock the swag, Rae Sremmurd
Make you hit them high notes, like you a tenor
Tell the big appetite, girl, you my dinner
I know they could do you, but I could do it better
Bring me out to London, yeah (U.K.)
I can show you somethin', yeah (somethin')
Unlock your clothes off your body
Give you lovin', yeah (let's get it)
'Cause that's how we do (that's how we do)
You wantin' me too (wantin' me too)
Your top be see-through, ooh (top be see-through)
I like the preview (like the preview)
We not there yet, girl, but we on the way (way, way)
We on the surfboard, yeah, we ridin' waves (waves, waves)
Let's get it going, girl, let's ándale (ándale)
Let's ándale (ándale), sip this champagne (ah)

Charli XCX

Charlotte Emma Aitchison (born 2 August 1992), known professionally as Charli XCX, is an English singer-songwriter known for her eclectic style. She began making music at fourteen, and her debut release was a 2008 limited-edition album aptly titled 14.

By 2010, Charli signed to Atlantic Records, and released her debut single “Stay Away” in May 2011. She released her “real” debut album, True Romance, in 2013. The record met critical acclaim but failed to attain much commercial success. Charli’s true breakthrough came with the release of hit collaborations like Iggy Azalea’s “Fancy” and Icona Pop’s “I Love It.”

In April 2014, Charli found solo success with “Boom Clap,” which was featured on the soundtrack of The Fault in Our Stars. It’s now certified triple platinum in the United States and gold in her native United Kingdom. Her sophomore album, Sucker, was a pop-punk oriented effort and enjoyed more success than her debut. “Break The Rules,” “Doing It” (featuring Rita Ora), and “Famous” all performed well on the UK singles chart.
