Jessie J showed her pipes are Pitch Perfect when she sang the signature song for the PP2 soundtrack…
AND we know she's capable of cranking out crazy hits (we still can't get Bang Bang out of our heads).
But, if you think these excellent examples of pop prowess are new to the British beauty, think again! Not only did Jessie write Miley Cyrus' jam Party in the USA, but she's been flaunting her ridiculous riffs and brilliant belting for years!
Not too long ago, the 27-year-old was sharing her incredible voice with the world by uploading webcam videos to YouTube.
Ch-ch-check out some of her best performances in honor of Flashback Friday (below)!
Big White Room in her LA bathroom
This is probably the most iconic of her webcam uploads! Big White Room is a beautiful ballad that allows the pop star to sing at the top of her lungs and show off some impressive runs — not to mention bathroom acoustics are AHmazing! This vid actually inspired Jessie to continue the tradition of singing Big White Room in bathrooms! LOL!
Mamma Knows Best in her bedroom
Donning Prince PJs and sitting cross-legged on the floor, Jessie goes all out in this rendition of her fun, jazzy track Mamma Knows Best! The song — a favorite audition selection among singing competition contestants because of its range and runs — features how effortlessly our girl can just let loose and bring the house down!
I Have Nothing cover
Many have tried to cover the late, great Whitney Houston, but only an elite few have succeeded. Consider Jessie J one of those musical masters. Sure, she may need to read the words of her screen, but we can't fault her for that when she sounds so flawless!
Nobody's Perfect — acoustic version
Here, Jessie takes a break from the backing tracks and enlists the help of a guitarist named Ben to transform her upbeat pop track Nobody's Perfect into an emotional ballad. Listen to her sing about how it's in human nature to mess up sometimes, and prepare to be floored by her flawless rendition.
Stand Up on her bedroom floor
In part two of her pajama performance, Jessie tackles her feel-good, reggae-esque song Stand Up, after providing a lengthy introduction where she adorably announces she's in the process of cleaning her room, which is why her bed doesn't have any sheets on it. Enjoy!
At Last cover
In this clip, Jessie takes on the Etta James classic At Last, filling the empty space between the verses with sweet ad libs. Even though there's a basketball game playing on the TV in the background, we doubt you'll even pay any attention because her runs are just so captivating. Especially the one at the end.
See? We're not wrong. Jessie J is a truly incredible artist and a vocal powerhouse.
But if for some reason there is STILL any shred of doubt in your mind — which there totally shouldn't be — we dug up a clip from when she won an award for Best Young Pop Singer at only 15 years old.
Ch-ch-check out the video (below) at around 4:17 to watch a teenage Jessie blow everyone away with her cover of Oleta Adams' classic ballad Get Here.
Oh, and she covered it again on Instagram Thursday, just because she was procrastinating when she was supposed to be getting ready for her day.
