Jessica Simpson has gushed over her sister Ashlee Simpson's "epic" return to the stage.
Ashlee celebrated the 20th anniversary of her debut album Autobiography by throwing a party at West Hollywood nightclub Evita on Saturday night.
Taking to Instagram on Sunday, Jessica shared several videos showing her younger sibling performing on stage and gushed over the gig.
"I woke up this mornin' cryin' like a fan girl nerd sister watchin' this from last night!!! You are a f**kin' rockstar Ash!" she praised. "You looked, sounded, and moved like you never missed a day on stage. It was simply EPIC! What a beautiful moment with all of your back up singers (the entire crowd)...CHILLS...You were born for this!
"Make a record asap! Let's tour together and take the kids! I am so proud to be your sister!!! You are INCREDIBLE!"
In response to Jessica's tour suggestion, Ashlee responded, "That would be fun!" and "Awww I love you sooooo much."
The singer-songwriter originally dropped Autobiography in July 2004, with the single Pieces of Me topping the music charts.
To celebrate the album milestone last week, she also released an expanded edition with three bonus tracks.
Ashlee hasn't released an album since 2008's Bittersweet World.
However, she has had some acting roles in recent years and appeared in the 2018 reality TV series Ashlee+Evan alongside her husband Evan Ross.
