The I’m a Celeb host went braless in the photo while wearing a top she referred to as an “under shoulder boulder non holder”.
Morris joked in the caption the unique outfit was what she was planning to wear to day one of the Coachella Music Festival in California.
The photo racked up more than 10,000 likes, with a number of celebs commenting on the post.
“Wow sexy underboob,” wrote radio star Jackie O.
“God I love you,” Studio 10s Angela Bishop said.
“This has made my year so far,” wrote Anthony Callea.
Morris followed up her hilarious selfie with another bizarre Coachella-inspired outfit.
She captioned the second photo: “Haven’t seen anyone else with the large Portuguese design #TootsieTote at Coachella yet”.
Play School presenter Jay Laga’aia wrote a cheeky comment on the photo, saying, “Have you considered waxing?”
