NOTHING is too good for KIM KARDASHIAN’s new baby – and the reality-show diva is sparing no expense for the upcoming delivery.

In fact, a source says the tab for the birth may top one MILLION dollars!

“This is not going to be just any delivery, even by celebrity standards,” a source told The ENQUIRER. “Kim has already spent tens of thousands of dollars to make sure things go down without a glitch.”

According to the source, Kim – whose baby with Kanye West is expected to arrive in July – has spent the past three months planning every detail of the birth.

She’s hired a top photograph her to document the delivery and her first week as a new mom – at a cost of $1,000 a day. And she and Kanye are also planning to dish out more than $4,000 per day for a deluxe birthing suite at L.A.’s Cedars-Sinai Medical Center, where Kim is expected to spend at least three days.

The posh maternity suite features a full-size soaking tub, two beds, a separate sitting room with a sofa and dining table, a flat-screen TV, a fridge stocked with juices, water and food, and two bathrooms. If that weren’t enough, Kim, 32, is spending thousands to have the suite blanketed in dozens of white roses. And although the new parents will receive three gourmet meals daily, Kim’s put some of her favorite restaurants – like Ruth’s Chris Steak House, and her local deli, Cuvee – on call for the duration of her stay.

In addition to the deluxe digs, the couple spent $25,000 on lingerie while they were in Paris last month, because Kim “had no intention of wearing a plain old hospital gown that’s been worn by other women,” the source said.

She also shelled out a small for­tune on organic clothes and sheet sets for the baby. Her favorite bou­tique? L.A.’s The Little Seed, owned by former “Punky Brewster” star Soleil Moon Frye.

Kim’s booked her favorite hair­dresser, Scott Cunha from the Andy LeCompte Salon in West Hollywood, to keep her perfectly coiffed – at a rate of $1,500 per day for three days.

The couple also dropped $1,500 on a top-of-the-line Orbit Baby stroller/car seat system to make sure their bundle of joy leaves the hospital in style.

BUT it’s Kim’s “Push Present”a gift a woman gets from her partner for pushing the baby out – that may send the total cost into the seven-figure range.

Mariah Carey got a $12,000 pink diamond necklace when she had twins Monroe and Moroccan two years ago, and Jennifer Lopez received a Canary diamond ring and matching earrings worth $2.5 million after the 2008 birth of twins Max and Emme.

“Kanye better have done his shopping,” added the source. “Kim is expecting a huge reward for all the months she’s spent with swollen feet, a big weight gain, morning sickness and a massive baby belly.”
