Jessica Simpson shows off family's Halloween costumes

LOS ANGELES, Nov. 2 (UPI) -- Jessica Simpson showed off her family's Halloween costumes in a new photo Tuesday.

The 36-year-old designer shared a picture of herself and husband Eric Johnson as Sandy and Danny from Grease, with 4-year-old daughter Maxwell as a parrot and 3-year-old son Ace as an octopus.

"When your kids are old enough to choose their own costumes... #HappyHalloween from my parrot & octopus!" she captioned the snapshot on Instagram.

Simpson also struck a pose for a couples photo with Johnson. The star, who wore a curly blonde wig, formfitting black top and pants and red platform shoes, joked about her ample chest in the caption.

"Danny Zuko and 'Sandra Double Dee' #AboutLastNight," she wrote.

Simpson and Johnson, a 37-year-old retired NFL player, welcomed Maxwell and Ace in 2012 and 2013, respectively. The couple married in Montecito, Calif., in 2014 after four years of dating.

"[Maxwell] definitely lets her brother know that she's the oldest and that she is charge," the designer told People magazine in April. "Ace is finally starting to stand up for himself."

"[The kids] are always very chill in the car unless they're bantering back and forth," she added. "Then me and Eric just have to tune them out. Just let them talk back and forth and get through it. They're brother and sister!"

Simpson last released the holiday album Happy Christmas in 2010 and teased new music in May. She continues to oversee her Jessica Simpson Collection fashion line, which she launched in 2006.
