Paris Hilton is sparing no expense when it comes to introducing her kids to their famous mom's lavish lifestyle.

The Simple Life alum, 42, along with her husband Carter Reum, also 42, went all out over the weekend as they celebrated their son Phoenix Barron's very first birthday with a star-studded themed birthday party at home.

Last year the couple became parents twice-over: they surprised their families and fans alike when they announced the birth of their first son together in January, and did the same for the arrival of their daughter London Marilyn in November.

For baby Phoenix's first birthday, Paris opted for a "Sliving Under the Sea" theme, a nod to her signature slogan, a mix of the words "slaying" and "living."

The party, which saw attendance from fellow moms and dads Rumer Willis, Kelly Osbourne, Lance Bass, and more, featured plenty of entertainment for both the kids and adults, from yummy treats to play time with farm animals.

The mother-of-two appears to have perfectly pulled off exactly what can be trickiest about a kids' birthday party, making sure everyone of all ages has something to enjoy.

Kadie Roberts – who has close to a decade of experience in party planning for several high-end event companies, including her own – explained to HELLO! that while kids' birthday parties lend themselves to more creativity and "a bit of whimsy," they also require more patience.

She said: "This also makes them one of the more challenging events to go off without a hitch," adding: "If you're not thoughtful in the details, the party can feel disjoined when attempting to engage so many different age groups and demographics in the same place, at the same time."
