The glamour model, who was evicted from the house earlier tonight, insisted that the former Hills stars are genuinely nice people.
"They're really nice people," she told Brian Dowling. "Genuinely they've got good hearts."
Speaking of Speidi's dramatic return to the house, Lacey added: "It was horrible. They hadn't done anything horrible to me so why did I say horrible things about them?"
She continued: "I did find it really hard because I was the youngest person in the house. Rylan was very much with the mums, and then there were the dads and I didn't find my place properly.
"They're bigger celebrities. It was horrible to be up against Rylan and Claire, and even Heidi and Spencer are really nice."
Lacey had previously clashed with Heidi after stripping naked in front of her to shower.
