The Only Way Is Essex stars Amber Turner and Dan Edgar have sparked split fears as it was noticed Dan had unfollowed Amber on Instagram.
Amber and Dan, who began dating in 2017, have faced rocky periods in their relationship over the years.
However, in recent years the couple moved in together and bought a dog, a goldendoodle called Oliver, together.
But, it appears the pair are facing tough times again as Dan, 32, noticeably no longer follows Amber, 29, on Instagram.
Dan's Instagram feed also no longer features photos of himself featuring Amber – hinting he has deleted photos of her from his profile.
Amber still follows Dan on Instagram while her profile also still features snaps of Dan – but the latest upload including Dan was posted in February.
Fans have taken to Dan and Amber's posts to comment and quiz them on if they're still together.
One wrote on Amber's latest post: "Have you and Dan split up?"
Another asked: "@amberturnerx where’s Dan is he not following you. Hope everything’s OK."
"Split??," a third penned while one wrote on Dan's latest post: "This breakup was a long time coming!"
Amber is currently holidaying in Dubai, UAE, and has been uploading solo snaps of herself enjoying the trip, hinting Dan hasn't jetted off with her.
Meanwhile, the latest episode of TOWIE, which is pre-recorded saw the couple enjoying a date in Thailand.
In scenes, which aired on Sunday evening on ITVBe, Dan is seen telling Amber: "It's nice to be away just me and you and doing something on our own."
Amber agreed with: "I know, it's nice."
The couple have been in an on-off romance since first getting together in 2017.
Dan, who previously dated Kate Ferdinand, and Amber split in 2018 and 2019 but rekindled things each time.
TOWIE star Dan was also romantically linked to Chloe Sims in 2019, while he was split from Amber. Chloe accused Dan of "destroying" her as she was abused online when their relationship was revealed.
Amber moved into Dan's bachelor pad and the pair bought a dog, Oliver, together.
And, six months ago, the couple took another step in their romance as they bought a luxury pad in Essex together and even hosted a housewarming party in the latest series of the reality show.
As the couple made the move, Amber opened up to fans on social media: "And just like that we are moving!! Happy & sad all in one…Breakups, makeups, arguments & some of the happiest memories ever! Where we brought our little baby Oliver home too! Will be sad to leave but excited for our next chapter…"
Last year, it was reported the pair were on the rocks after TOWIE's Ella Rae-Wise claimed Dan touched her in an "inappropriate" manner during a night out.
It was claimed by Ella, 22, Dan had touched her waist and held her hand. She later clarified her comments, insisting he didn't touch her without consent, but questioned whether he should be behaving that way when he had a girlfriend.
Dan and Amber hit back at reports and continued their romance as Dan said the matter was "being dealt with legally" while Amber said the claims were "categorically FALSE".
