Kim Kardashian and Britney Spears cozy up in bed during fun-filled sleepover with Khloé

Pillow fights and feathers, overdosin’.

Britney Spears’ song “Slumber Party” became her reality Friday night, as she was seen cozying up in bed with Kim and Khloé Kardashian, 41, in two selfies posted to Instagram.

The “Toxic” singer, who was joined by her longtime manager, Cade Hudson, appeared to be visiting the SKIMS founder’s Hidden Hills home.

“Calabasas nights,” Kim, 45, wrote atop the first image in her Instagram Stories. She struck her signature pose as Spears, 43, stuck out her tongue in the cheeky snap.

The second photo, taken by Hudson, showed the four sitting next to each other in the bedroom, with a large, pink mood light behind them. Kim sported a black robe with her hair in a slicked-back bun. Khloé, on the other hand, opted for a pair of Christmas-themed pajamas and wore her tresses down in loose waves.

As for Spears, she wore a yellow-and-white ensemble.

While the hangout may be unexpected, Kim and Spears have known each other for quite some time. The “Kardashians” star even spoke out with “empathy” after watching the documentary “Framing Britney Spears” in March 2021.

“The way the media played a big role in her life the way it did can be very traumatizing,” she wrote on Instagram at the time.

“It can really break even the strongest person. No one deserves to be treated with such cruelty or judgment for entertainment.”

It was also previously reported that Kim wanted to help Spears break free from her 13-year conservatorship.

“She reached out to Britney as soon as she read her [court] statement,” an insider told Closer magazine back in 2021.

“Kim knows she’s going through hell and that her situation is like a jail sentence. She let her know she’d do whatever she could to help her win her battle,” the source added.

“Britney has given the green light to let Kim help in whatever capacity she can and asked her to email her lawyer, Samuel Ingham. She really appreciates her support.”

A judge ultimately terminated the guardianship in November 2021.

Kim and Spears, who are both friends with Paris Hilton, reportedly met in the early 2000s. The duo were last photographed together at a 2012 Grammy Awards party.
