Kate Moss never wants to marry Jamie Hince.
The British supermodel has no plans to wed The Kills rocker, who she has been dating for around two years, is concerned about the stability of the relationship and has no plans to fully commit.
A source said: "Kate says she doesn't want to get married and that's that.
She doesn't believe in it and her beliefs have become more certain now as she and Jamie are rowing more and tension is high.
"Kate has seen her pals' marriages fall apart and doesn't want to put herself or her daughter Lila Grace through that, she doesn't see the point."
The couple recently went on holiday to St. Tropez, but their relaxing break was marred by arguments.
Kate - whose daughter Lila Grace, from her relationship with magazine publisher Jefferson Hack, is now six - invited singer Lily Allen to join them, leaving Jamie furious.
He was further enraged when Kelly Osbourne arrived, and is concerned his 35-year-old girlfriend no longer enjoys spending time with him.
The source added: "Jamie was fuming and couldn't understand why Kate kept inviting her friends on their family holiday.
"Kate's comments about marriage will shock Jamie though, as he has had plans to propose for a while and he really wants to marry Kate. But, on some level at least, he must have been expecting it."
