JOJO Siwa is believed to be 'wearing Chris Hughes' ring', according to eagle-eyed Celebrity Big Brother fans.
The US star was captured on film with a silver ring on a chain around her neck and fans are convinced it belongs to Chris.
Chris, 28, was previously pictured wearing a very similar ring on his finger during a night out with a male friend.
And after 21-year-old JoJo touched down back home in Los Angeles, supporters of the pair are convinced he has given it to her.
JoJo filmed herself walking down the street and the silver ring was clearly visible on her chunky necklace.
In the clip, she told her Instagram followers how she is struggling to adapt to life back in the US following her CBB stint.
"Now that I'm back, I want to tell you the weirdest thing that's happened since being in the the Big Brother house, slash being in the UK for a long time," she said.
"Nothing that I liked prior to leaving, I like anymore. It's the weirdest thing.
"Like, now at breakfast, the things I would normally order I'm like, I don't want them. I don't know what to eat."
JoJo also said she has gone right off a particular brand of protein crisps she liked, called Quest Chips, and prefers cups of tea to energy drinks.
"Yesterday, I was like, I don't want these [chips]. I want a Hoola Hoop."
The Dance Moms star did not mention the ring around her neck.
Fans, however, were straight on it.
Writing on X, formerly known as Twitter, one said: "Ok, I might possibly be delusional lol but the ring that JoJo has attached to her necklace in the video on her Instagram page today looks SO SO similar to the ring Chris usually wears!! Could he have given her his ring?!"
A second fan replied: "Definitely the same ring."
Someone else agreed: "Well spotted, I think you are on to something there."
JoJo and Chris built a close friendship during their time on CBB, with viewers regularly commenting on their chemistry and emotional bond.
Before heading back home to the States, she dumped her now-ex Kath Ebbs at the show's wrap party last Friday night.
JoJo has since sent fans into a spin by liking a romantic fan-made video of herself and former Love Island star Chris.
The video was captioned, 'Take me back to the night we first me' and JoJo was quick to show her appreciation by clicking the heart icon.
She has also give her first in-depth interview on The Viall Files podcast since arriving home.
JoJo spoke candidly about her perspective on her relationship with Kath while in the TV house and insisted her decision to end it had nothing to do with fellow housemate Chris.
The singer and dancer revealed the penny dropped that she was unhappy with Kath when she looked at a photo from home.
JoJo said: “I remember looking at my photo, because everyone was looking at their photo. Jack had his partner, Mickey had his dog, Chesney had his family, everyone had their photo.
“And I had mine as well and it was a group photo with a few people in it and I remember thinking, uhm, I wasn’t happy this day.
“And I remembered why I wasn’t happy this day. And now I’m here looking at this photo realising there is not a single reason I should not be happy this day. I’m with my family in Disney World and it’s Christmas.”
