Before meeting Parisi, Brook had several public romances with high-profile figures. She dated actor Jason Statham from 1997 to 2004, during which time they were reportedly engaged.

Reflecting on their split years later during an appearance on the How to Fail podcast, Brook discussed how their differing career paths affected the relationship.
"I tried to have a baby but it didn't work...
You can feel quite a bit of failure if you go through miscarriage or fell that it's quite unfair, but as much as it was a real loss and a difficult time, I got through it," said Kelly Brook, television presenter, referring to a miscarriage she experienced during her subsequent relationship with rugby player Thom Evans.
Following her relationship with Statham, Brook was engaged to actor Billy Zane after meeting on a film set in 2004, though the pair separated in 2008.
She was later engaged to Evans until 2013, and had a brief engagement in 2014 with Gladiators star David McIntosh.
Describing her feelings during her past engagement to Zane in a quote previously reported by Digital Spy, Brook expressed how deeply invested she had been in that relationship.
"I fell in love with Billy and felt like I was under a spell," said Kelly Brook, television presenter.
"They say love is an illness and I do believe that. I became lovesick."
During her relationship with McIntosh, Brook announced their engagement online shortly after they met at a New Year's Eve party.
"Lovely weekend in Wigan meeting my new extended family," said Kelly Brook, television presenter.
"Such happy times and excited to share my life with the most wonderful man I've ever met."
