Jessica Simpson and Ashlee Simpson Ross are ready to put the spotlight on their dad.
On Saturday evening, the famous sisters stepped out to show their support for Joe Simpson's first art show titled "Dreams Work."
Held at the Bruce Lurie Gallery in Culver City, Calif., the grand opening allowed guests including Evan Ross and Eric Johnson to witness their family member's finished products up close and personal.
As for how it was to direct two talented stars in Hollywood, Joe admitted that he was very fortunate to work with two naturals.
"[Ashlee and Jessica are] so professional. They're so good and they know how to work a camera," the proud dad gushed to E! News' Erin Lim. "They know their stuff."
The show, which helps benefit Adopt the Arts, includes photographs of Joe's two daughters and is expected to be on display at the gallery throughout the upcoming week.
And while we can only imagine how proud Ashlee and Jessica were of their father's latest project, it's the happiness Joe sees in his own kids that makes him the most content.
"Their joy makes me happy," he explained. "As a father, it's not what your children do. It's who your children are and are they happy? That's the question you'll always ask."
With busy careers and a jam-packed home life that includes adorable children, Jessica and Ashlee easily have their hands full. But recently, Jessica sparked rumors that she's working on new music.
Between her Instagram posts from a music studio and a scheduled appearance on the Today show's Summer Concert Series, we had to ask Joe if he knows anything about any new tunes. So what's the verdict?
"Trust me, I'm not the first who gets to hear it now," he joked to E! News. "[But] I live for when my children play me their music."
