Paris Hilton has changed a lot over the last 20 years … going from making sex tapes and partyin’ ’til the early morning, to becoming a mom and testifying before Congress.

The reality tastemaker broke onto the scene in the early 2000s … drawing international attention when her sex tape with poker player Rick Salomon leaked in 2003.

She had her own reality show at the time — “The Simple Life” — which featured her friendship with Nicole Richie … though the two had a pretty nasty falling out in ’05.

In the years since, Paris has embraced a calmer lifestyle … marrying Carter Reum in 2021 and raising her two children — London and Phoenix.
