Mr Hickman, 29, a window cleaner, said: "I showed my daughter Ami, who's six, and she saw it straight away, so I thought 'well if she can see it too it's not just me seeing things'."
Mother-of-six Miss Kelley, 34, went for her 20-week scan at Sunderland Royal as normal last month, but doctors could not see the foetus's stomach or diaphragm.
A few weeks later she was sent to Grindon Lane Walk in Centre for a closer look.
The more powerful scanner there is normally used to examine internal organs so the images it produces much more detailed.
Mr Hickman said: "We were looking at the pictures again, and I just saw Jacko there.
"None of us are really Michael Jackson fans. I mean I like him, but we're not crazy about him or anything."
The children Chris, 16, Amanda, 15, Jason, 13, Alisha, 10, Ami-Lee, 6, and Kye, 4, all see the famous singer's face in the scan photo too.
But the new family member will not be called Michael - the couple already know they are having a girl.
Miss Kelley is 24 weeks pregnant and due to give birth to her daughter in March. She said: "I've had plenty of scans before and none of the photos have ever looked like this one. It's a bit spooky really.
"But it is my seventh child, and they say seven is a mythical number."
