Fans saw the couple officially split on last night's episode of the ITVBe show, with Lockie moving his stuff out of the flat they shared together in Essex.
Their break up stemmed from the emotional holiday to Marbs, where Danni accused Lockie of treating her badly over the last few months, unaware he'd actually been hoping to propose in Spain.
Now, Danni has reacted to their split, tweeting a picture of her and Lockie together with the caption: "You will always be my best friend and have a special place in my heart."
She also told followers: "Hope everyone enjoyed tonight's #TOWIE feel very emotional tonight & all your lovely tweets really do put a smile on my face."
In Sunday night's episode, we saw Danni saying she had a clearer head now she was back in Essex.
She told the girls: "I love him but I don't feel like I'm in love with him. I think the respect has gone. How can a man who says he loves you speak to you like that? He's moved some bits out of the flat but not all of it. I want it all out. I want the key back. I don't think he realises how serious I feel. It's not just a break. I don't want to be with you. I don't want to be in this relationship."
Later on, she met with Lockie in the flat and they officially broke up. Lockie has since said that Danni can't backtrack on that and can't get angry if he starts to date other women.
"Even though she says we're single, she will still get massively jealous if she sees me talking to another girl. I know she will, 100 per cent. That's not right. You can't say you don't want to be with someone and still get jealous. I'm free to do what I want and she's lost the right to have any opinion on my life."
TOWIE airs Sundays and Wednesdays at 10pm on ITVBe.
