When Ashlee Simpson and husband Evan Ross — youngest son of the legendary Diana Ross — kick off their “Ashlee + Evan” mini-tour at Bowery Ballroom on Monday night, they will be worrying about a certain little stage crasher: their 3-year-old daughter, Jagger.
“We’re actually nervous for the shows, ’cause when we’re in rehearsal, she won’t get off the stage,” Ross, 30, tells The Post. “She literally won’t leave the stage. She’ll dance the entire time until the end of the set.”
It shouldn’t come as a surprise that Jagger — named after Mick, natch — would already be showing endless love for the stage: Both of her parents come from show-biz families, and now they’ve combined their musical DNA into the duo Ashlee + Evan, which released a self-titled EP in October.
The project marked a singing turn for Ross, who has acted in films (“The Hunger Games: Mockingjay — Part 1” and “Part 2”) and TV (currently on Fox’s “Star”), and a recording comeback for Simpson, who hasn’t released a solo album since 2008’s “Bittersweet World.”
“I had taken a very, very long break,” says Simpson, 34, who scored her biggest hit with “Pieces of Me,” her debut single, in 2004. “For me, it was just a time when parenting and being a mom was my sole focus.” (She also has a 10-year-old son, Bronx, with ex-husband Pete Wentz of Fall Out Boy.)
