Ashlee and Jessica Simpson's father Joe Simpson is "doing good" following his battle with prostate cancer.
The talent manager turned photographer began a fight for his health in September 2016 after being diagnosed with the illness, and 33-year-old singer Ashlee has now revealed her father is cancer-free and "healthy" once again.
She said: "It's such a blessing. He's doing good now and feeling good, I'm so happy he's healthy now."
Ashlee's husband Evan Ross - with whom she shares three-year-old daughter Jagger - added that whilst the experience was "scary" for the family, they're all happy things are looking up again now.
He added: "It was a really scary experience for Ashlee, for their whole family. So for me I was just trying to make sure I was there and paying attention to how everyone was feeling."
Ashlee and Evan, 30, are launching their own reality show entitled 'Ashlee + Evan' on E! this month, which will show off the "truly authentic" side of their hectic lives.
The couple admit the show works because they both have "a good understanding of each other", and were able to listen to one another when it came to implementing ideas into the program.
Evan told E! News: "We wanted to create something that was really, truly authentic to who we were. And so that people could really kind of get an understanding for the first time of where all of this is coming from and where the inspiration's coming from.
"It all comes from love. I feel like we really have a good understanding of each other and we're learning how to work with each other too."
This week, Ashlee - who also has nine-year-old son Bronx with her former husband Pete Wentz - and Evan celebrated four years since they tied the knot in September 2014.
