Kissing Other People - Lennon Stella Beltonen:

[Pre-Chorus]
But how do you know?
How do you really know
That you're not holding on anymore?

[Chorus]
Kissing other people
Oh yeah, that's how I know that your love is gone
That's how I know I'm really moving on
'Cause I don't feel guilty kissing other people
Oh yeah, losing myself in a new someone
That's how I know I'm really moving on
'Cause I don't feel guilty kissing other people
