"Dancing in the Dark" singer Dev -- also known as the voice behind "Like a G6" -- is front and center in a brand new sex tape, or so it appears ... and TMZ has learned it's currently being peddled to the highest bidder.
Sources tell TMZ, the tape was shot last year with an ex-boyfriend -- and it was done in the style of famed sex tape "1 Night in Paris" ... i.e. in the dark with green night vision on.
Other than that, it's pretty run of the mill as far as sex tapes go -- a woman who appears to be 23-year-old Dev (real name Devin Tailes) going at it with her then-boyfriend. Normal, boring sex.
In fact, it's so generic you might think the blonde chick was a normal, unfamous person -- if not for Dev's incredibly distinctive tattoos ... namely, a diamond on her front left shoulder and two sparrows on her lower back.
(Hummina.)
The tape's currently being shopped to media outlets by a third party. It's unclear how the tape was acquired.
Dev -- the singer behind the smash hit "In the Dark" -- is desperately trying to block her sex tape from going public ... claiming the mystery seller is just "someone trying to embarrass me."
We broke the story ... the footage is being peddled to various media outlets ... showing Dev with an unidentified male.
Now, the 23-year-old singer tell us ... “My boyfriend at the time and I were young and having fun, it was a long time ago."
She adds, "I am now a mom and engaged and have more important things to think about then someone trying to embarrass me.”
Still, Dev has fired off a cease and desist letter to various media outlets ... warning them not to publish the footage ... or else she'll be forced to go all lawyery on their asses.
At least she was classy about it, she's right. She has more important things to worry about. However I hope it doesn't leak, she's a mother for gods sake, that'd be like me knowing my mom had a ****o.
As hot as that tape would be, I don't want it to come out. Dev is going through so much **** already. This is the last thing she needs. Let's focus on that smash sophomore album
