The Ocean Eyes songstress has teamed up with the famous sneaker brand to deliver her very own shoes, and was desperate to show them off as she headed over to Instagram this week.
In one snap, Billie lay flat on her back with both legs raised in the air, with her denim shorts yanked down to expose her bare calves and ankle-length white socks.
The orange and white trainers took centre stage, before Billie turned her head to the camera in one sultry video and blew a huge bubblegum bubble.
In another shot, she arched her back while straddling two chairs with the shoes dangling in front of her.
Billie penned on Instagram: “My new @nike air alpha force lows are available now. Excited to share these with you.”
And fans, unsurprisingly, soon went wild, with one penning: “Billie is literally a religion.”
“I can’t focus on them shoes, that face of yours won’t let me,” somebody else agreed.
While a third social media user said: “This is my religion whatever it is.”
Billie was soon branded “fine as hell” by another passionate follower, while a fifth told her: “Billie you’re so hot!”
It comes after Billie shocked fans as she lay on the floor in a tiny crop top and fishnets, wearing a balaclava over her face as she arched her back to show off her curves.
Between her casual trainers and a pair of barely-there khaki shorts, the star – whose most recent track featured on the Barbie soundtrack – looked incredible as she flashed her flat tummy.
Over the top of the picture, she added Waka Flocka Flame’s hit track Hard in da Paint.
The Bad Guy hitmaker appeared to be using a public bathroom while she held her phone up to snap a picture with her legs spread on the tiled floor.
