Kourtney Kardashian refuses to feel left out.

After not being featured in a recent photoshoot with siblings Kendall and Kylie Jenner and sister Kim Kardashian, Kourtney decided to take matters into her own hands — sharing a mirror selfie on Friday.

The snapshot sees the Poosh founder posing in red lingerie while sitting inside a walk-in closet adorned with shoes, as well as various pieces of lingerie scattered across the floor. Kardashian was also seen rocking a lengthy braid and a skull and bones necklace.

"Since I wasn’t invited to the sister shoot …," Kardashian, 41, jokingly wrote on Instagram, referencing her sisters' photoshoot for Kim's latest SKIMS line. The shoot notably featured Kim, Kendall and Kylie all wearing red lingerie for Valentine's Day.
