Multi-platinum selling recording artist and actress Demi Lovato is a survivor, a fighter and a fierce force in the entertainment biz, and now the comeback kid is revealing another side of herself by guest starring on Robert Rodriguez's "From Dusk Till Dawn: The Series" on El Rey Network.

The 22-year-old actress, who has 16.7 million Instagram followers and 28.7 million Twitter followers, shared the news on both social media platforms. She also posted a picture of herself with renegade filmmaker Rodriguez who is both the series' creator, director and El Rey Network chairman and fellow cast member and boyfriend Wilmer Valderrama while on set in Austin, Texas.

"Me and the boss @rodriguez.... We worked #fromdusktilldawn.... Get it?? Y'all ain't ready...." Lovato wrote on Instagram.

The love-struck Lovato also showed Valderrama some affection on Instagram and posted a photo of herself kissing him on the cheek. Her post read:

"After a long night's work.... #fromdusktilldawn"

"From Dusk Till Dawn" fans are gearing up for the El Rey Network/Miramax series, which is set to return for an all-new second season on Tuesday, Aug. 25.

Lovato will join returning cast members: D.J. Cotrona, Zane Holtz, Jesse Garcia, Eiza González, Wilmer Valderrama, Madison Davenport, Brandon Soo Hoo and guest star Jake Busey.

The critically acclaimed supernatural crime saga has also welcomed more impressive talent to its sophomore season's roster including Danny Trejo ("Machete," "Machete Kills") as "The Regulator"; Esai Morales ("Criminal Minds," "NYPD Blue") as "Lord Amancio Malvado"; Jeff Fahey ("Lost," "Justified," "Texas Rising") as "Uncle Eddie Cruickshank"; and Briana Evigan (Step Up 2) as "Sonja Lam."

Lovato and Valderrama have publicly been huge supporters of one another, and they haven't been shy to share their love and affection for each other.

In March, Lovato celebrated her third year of sobriety. In 2010, she entered rehab and has been extremely candid about her struggles with depression, bipolar disorder, an eating disorder and cutting during her preteen and teenage years. At the time, she also took to social media to give a touching shot out to Valderrama, saying, "She wouldn't be alive if not for him," ABC News reported.

"I wish I could put into words how grateful I am for this man right here," she wrote on Instagram, alongside a photo of the two of them kissing.

She also professed her unconditional love for "That '70s Show" actor/producer and Voto Latino co-founder.

"But my love has grown to a level that words could never possibly express how much this man completes me. He's loved me the way I never thought I deserved to be loved and with this day marking my third year sober," she said.

"After sharing my ups, putting up with my downs and supporting my recovery, he still never takes credit and I want the world to know how incredible his soul is. I really wouldn't be alive today without him. I love you Wilmer."

Hours before Lovato's Instagram post, Valderrama posted a heartfelt message to the singer.

"Today, we lay another stone together," he wrote on Instagram.

"It is now 3 years since you said: I am more important then any past, demon, disorder or addiction.. Where you decided that YOUR life was worth living while loving yourself.. And I'm sure glad you did... I knew then the woman you've become now.. I am proud and honor to be front row to see the world you are about to change."

A Texas native, Lovato, who must have felt at home during the shooting of "From Dusk Till Dawn," is currently working on her fifth studio album. In 2013, her career catapulted with her redefining album "Demi," which included her hits "Heart Attack," "Really Don't Care" and "Neon Lights."

Following the album's release, Lovato appeared in the hugely popular FOX series, "Glee," where she became a guest star favorite.

In 2014, Lovato set off on two record-breaking arena tours including her "Neon Lights" tour, which reportedly grossed 8.6 million over 21 dates and the "Demi World Tour," which made stops in North America, Europe, Australia, Asia and New Zealand. Also a philanthropist, Lovato's book, "STAYING STRONG: 365 DAYS A YEAR," became a New York Times bestseller.

"From Dusk Till Dawn: The Series" premieres on Tuesday, Aug. 25, on El Rey Network at 9 p.m. ET.
