A friend of the Strictly Come Dancing star claimed that she was struggling to deal with not being in a relationship anymore.
Brook revealed that she had ended her four-year relationship with the Titantic actor last week.
Pal Natassia Malthe told The Sun: "Break-ups are always hard but Kelly is just getting on with things. But I think she misses being in a relationship.
"She’s a real relationship person and she loves all the cuddles, kisses and support that comes with it."
It is rumoured that Brook broke off her engagement to Zane because of comments her father made about their relationship before he died last year.
