Fifth Harmony's Camila Cabello surprised fans of the group last year by teaming up with Shawn Mendes for a song called "I Know What You Did Last Summer" and she now has another solo offering up her sleeve. 

The singer-songwriter has collaborated with rapper Machine Gun Kelly on a brand new track called "Bad Things", which she has been teasing in short audio clips shared to her Twitter page. Their song will officially drop tomorrow (October 14), but the audio has leaked online today. 

The lyrics Camila has shared from the track so far include, "I want you forever/even when we're not together/scars on my body/I can look at you whenever" and "Am I out of my head?/Am I out of my mind?"

Earlier this week, it was revealed that the 5H beauty has created a T-shirt to raise money for Save The Children. For more information on where you can buy Camila's specially designed T-shirt, click here.
