ET's Sophie Schillaci spoke to Ashlee and her husband, Evan Ross, at Clive Davis' 2019 Pre-GRAMMY Gala at the Beverly Hilton Hotel on Saturday, where she gave an update on her older sister.
"She's doing good," Ashlee said of Jessica. "She's doing great."
Ashlee, 34, also admitted that even she was alarmed when Jessica, 38, Instagrammed a picture of her severely swollen feet last month.
"I don't know where we were but I was like 'Are you OK?!'" she said with a laugh.
The couple definitely had family on the brain thanks to Evan's mom, the legendary Diana Ross, being celebrated at the GRAMMYs this year with a show-stopping 75th Diamond Diana birthday performance. Both Ashlee and Evan named Ross as their favorite Motown artist when asked, and Evan recalled his childhood memories attending the always star-studded Clive Davis pre-GRAMMY parties.
"Clive's party is amazing," Evan said. "It's probably my favorite night of all. I've been coming here since I think I was 12 years old. And one year I think I jumped on a table and started singing one of the songs."
Meanwhile, Jessica stayed home GRAMMY weekend, and shared her sense of humor when it comes to her pregnancy. The mother of two -- who's currently expecting a baby girl with husband Eric Johnson -- Instagrammed a picture of herself having trouble squeezing through cars with her baby bump.
"Tight squeeze but I’m pushin’ through," she joked.
