Kourtney Kardashian has been focused on her children and herself after splitting from her longtime boyfriend Scott Disick over the summer, and she proved it by sharing two back-to-back photos on Instagram. The "Keeping Up with the Kardashians" star snuggled with her kids and showed off her toned body in two posts, Us Weekly reported.

Kardashian, 36, posted an adorable snap of her feet along with two other little pairs, all dressed up in black-and-white skeleton pajamas. Her feet were tangled up with 5-year-old son Mason's and 3-year-old daughter Penelope's while all three of them snuggled up in bed.

"Skeleton cuddles," Kardashian captioned the shot.

In the second photo, Kardashian posed in black low-rise leggings, Nike sneakers and a sexy sports bra with her long dark hair tied back in a tight pony tail. She held her phone up, covering her face slightly in the mirror pic.

"Working out is one of the only things that helps when I'm feeling anxious," she wrote in the caption.

The mom of three has a lot to feel anxious about these days. She posted the photo just days after returned from Las Vegas, where she offered support to her sister Khloé Kardshian. Khloe had kept vigil by her estranged husband Lamar Odom's side as he laid in a coma for three days following a drinking and drug binge at Dennis Hof's Love Ranch, as previously reported by HNGN.

While Odom was being hospitalized, Kardashian's ex-boyfriend Disick entered rehab for the second time this year, as previously reported by HNGN. Disick reportedly checked into rehab to increase his chances of winning unsupervised visits with the former couple's three children, Mason, Penelope and 10-month-old Reign.
