Selena Gomez 'Everybody Knows (Douchebag)' Music VIDEO: 'Come & Get It' Songstress Disses Ex-Justin Bieber in Dustin Tavella's New Dance Hit with Danny Trejo?

Back in March, Selena Gomez and a slew of her close gal pals (including "Secret Life Of The American Teenager" starlet Francia Raisa) posted a viral video dancing along to Dustin Travella's new hit "Everybody Knows (Douchebag)." Gomez and her posse made a name for the aspiring singer on Youtube thanks to their sexy dance routine... and Travella was so grateful, he had the "Come & Get It" beauty star in the official "Everybody Knows" music video! Hmm... is Gomez totally dissing her pop star ex-boyfriend Justin Bieber by appearing in the video? Check out the clip below and decide for yourself!

Here's Gomez's original choreography to "Everybody Knows (Douchebag)":

And here's Travella's OFFICIAL music video, just released on Thursday (June 27):

Gomez makes an appearance at around the 4:20 minute-mark in the rather amusing video (also starring actor Danny Trejo).

Here's the lyrics:

Do you really wanna be with him, girl?
When all he ever does is make you cry 
And do you think that you can handle the truth girl 
When all he ever does is tell you lies 
You know what.. 

He kisses you but he don't mean it 
And he don't look into your eyes 
And he don't see the things I see girl 
So somebody tell me why..

Your boyfriend is a douchebag 
And everybody knows 
Your boyfriend is a douchebag 
Your momma told you so.

You know he's got somebody on the side, girl 
And the way he talks to us is a sin 
He just keep sinnin' on..
I really think it's time girl
You quit defending him 

You keep telling me things are gonna change 
yeah, okay. 
Will you could never change my mind. 

Your boyfriend still a douchebag 
And everybody knows 
Your boyfriend is a douchebag 
Your momma told you so.
And everybody knows 
Your boyfriend is..
You got to let him go!
Your boyfriend is a douchebag 
Even his momma thinks so. 

There ain't no way around it 
you really gotta know 
that cover up is sweet but phony got that candy coat 
You try to make the truth 
Look like it's something good 
and you perform like he's a star reppin' Hollywood 
I know he said he's sorry 
But I see nothin real 
And yet his mouth keep runnin' track and field. 
SO maybe you can help me 
understand why you do do do do that!

And tell me why your boyfriend's a douchebag 
Girl, everybody knows
your boyfriend's such a douchebag 
Your momma told you so, 
you know what she said.. 

You gotta let it go, go!!! Go!! Go!!
Gotta let him go!! Go!! Go!!!

Take that, JB!
