Lauren Conrad and Audrina Patridge have both commented in recent weeks that the stars of The Hills have not kept in contact since the MTV series ended in 2010.
Port – who also starred in The Hills spinoff The City - has now told People that's perfectly natural for the Hills cast to have moved on with their lives.
"I think we all kind of went our separate ways once the show ended," Port explained, adding: "I'm fine with it, like I'm at peace with it."
She added: "With me, I never feuded with anyone, and nothing ever ended badly, so it just naturally happened that [I lost touch with people]."
Port also hinted that she might return to reality television in the future.
"I think I would do something fashion-related for sure," the star said. "But I don't ever see myself doing something as intimate as what I did."
Her own series The City aired on MTV for two seasons between 2008 and 2010.
Port currently serves as a judge on Britain and Ireland's Next Top Model alongside Tyson Beckford, Julien MacDonald and Elle Macpherson.
