Kelly Brook "doesn't have the instinct" for marriage or kids.
The 41-year-old beauty has been with her boyfriend Jeremy Parisi for years, but she's not desperate to have kids or tie the knot.
She said: "I’ve got a bucket list and I have to say a wedding is not on it!"
The brunette beauty - who has previously dated the likes of Thom Evans and David McIntosh - also insisted that motherhood "isn't on her radar" at the moment.
Kelly told Notebook magazine: "I feel like marriage and children are not things I’ve wanted. I like travelling and being with my partner, I like animals working and being independent and I like my freedom. I like being spontaneous.
"There are so many things I love, and I think marriage and children would stop me doing those things. I try to imagine how it would be, and when you have children it’s a huge commitment.
"It’s very hard to change your ways when you get to your 40s and I don’t think it’s for everyone. I’m not saying never, it’s just not on my radar."
Kelly and Jeremy first started dating back in 2015 and while she occasionally thinks about marriage and kids, she insists she simply doesn't have the "instinct" for it.
She said: "I think about it every now and again, then I quickly forget about it. I just don’t have that instinct."
Previously, Kelly suggested that Jeremy, 34, still has lots of ambitions he'd like to achieve and was too young to get married.
She shared: "He’s a lot younger than me and still has lots of things he wants to do in his life. So I’m not going to start pressuring him."
