Is she sticking out her tongue!?

They never told me! I just got my gender sonogram today (YAY!) and the sonographer took screen shots, but as I'm looking at this one, it looks like she's maybe sticking out her tongue? Or is that her lips! This is our first and only profile shot we have. ♥️♥️
Would a tongue be visible? 
I'm 18 weeks 4 days.
