The model told Closer that everybody was aware that the pair were destined to part.
She said: "The split is what it is. Everyone knew it was never going to be a life-long thing.
"She'll bounce back, she's fine now."
Pixie added that she would soon give up her modelling career and instead enrol on a fine art degree and work hard to succeed at the subject.
Last week, it was reported that Peaches had not told her family about her divorce before the news hit the internet.
It was also claimed that an affair between Peaches and singer Donald Cumming was the reason for the split.
