Demi Lovato and Wilmer Valderrama are more than just a couple, they're now co-workers as the singer is joining her other half in the critically-praised TV show "From Dustk Till Dawn: The Series". 

Lovato, who has always been outspoken when it comes to her feelings for Valderrama, broke the news on Tuesday through Instagram. She posted a photo of her and the 35-year old actor while on set in Austin, Texas.

She captioned photo "After a long night's work..."

The 22-year old singer and actress has also posted another snap with the series creator Robert Rodriguez, who has had blockbuster productions in the early 2000s, including the 'Spy Kids' in 2001 and the 'Sin City' in 2005.

She captioned "Me and the boss @rodriguex... We worked #fromdusktilldawn... Get it? Y'all aint ready.."

Though none of the casts have talked about Demi's role on the show, the fans must already be on the lookout for their idol's appearance.

On the other hand, fans of the series should expect more darkness next season as the horror TV series will "be a little more twisted. Every character will go through their own personal hell," according to Valderrama. 

The off- and now on-again couple seem to be playing characters on the show quite opposite their real personalities. While the details have not been fully revealed, the "Skyscraper" singer was spotted running after a bank robbery incident that left several people dead. 

Valderrama, on the other hand, portrays a brutal criminal overlord with an interest in the paranormal, a far cry from his character Fez from That '70s Show.

The second season of  "From Dusk Till Dawn: The Series" 'Season 2' will premiere on August 25 via the El Ray Network. The new season will have 10 episodes, produced by FactoryMade Ventures in association with Miramax.
