The fan favourite couple have been through a multitude of ups and downs during their time on the show, including a near-engagement in Tenerife and an eight-month break, but when they rekindled their relationship in April, many thought the fairytale was firmly back on track.
But were we wrong?
Despite looking totally smitten and loved up in pictures and on the show, Danielle admitted to Kate Wright she's questioning the future of her romance.
"Me and James aren't perfect," she admitted. "Looking back now, I got back with him because it was hard being around him. Why are relationships so hard?"
And she elaborated later on at a circus-themed party for Bobby Cole Norris' 30th birthday, saying she's just not sure if Lockie is really the one.
"When I gave James another chance I thought everything I kind of wanted would be, but it's not," said Danni. "And I don't know if he wants the same sort of things as me still. I do think James sometimes says things to please me. Is he still the one? I'm at the age now where I'm questioning things."
The episode ended with Danielle and Lockie at separate ends on the party, with Lockie looking particularly sad as he sat alone. Fans were pretty stunned by all this and took to Twitter to share their concerns over the couple's future.
