Kourtney Kardashian cradles her newborn son Rocky while wearing a luxurious Versace gown in the new photo, “Bliss.”

Kourtney Kardashian posted a new photo with her baby son Rocky Thirteen Barker on Instagram on Sunday.

The 44-year-old reality TV star, who shares her son with husband Travis Barker, 48, posed in a white Versace gown while holding her newborn to her chest.

The snap appeared to have been taken with a Polaroid camera as it had a soft and luminous finish.

Kardashian's dark hair was straight and parted in the middle as it flowed down her back.

In a caption to her 224 million followers, she wrote one word: “Blisssss.”

In the picture, which racked up over 400,000 likes in two hours, Kourtney showed off a quick nude manicure.

She stood in front of a window that overlooked her picturesque, grassy backyard.

Earlier this month, Barker shared a sweet clip on Instagram of the couple caring for their baby in their bedroom.

Blink 182's drummer showed off his basketball skills as he attempted to throw paper balls into a trash can.

In the corner of the room, Kourtney sat cross-legged on a large lounger with Rocky on her lap.

And another recent post from the new mother – who has three children from her relationship with Scott Disick – featured a turquoise stroller by designer Jeremy Scott and Cybex.

The POOSH founder recently came under fire for referring to herself and Travis as “Rocky's parents” on social media.

Fans complained that she neglected to mention the couple's other children from previous relationships.

Kourtney shares Mason, Penelope and Reign with Disick, while Travis shares son Landon, 20, and daughter Alabama, 18, with ex Shanna Moakler.

“You have other kids too, huh?” one follower wrote, while another shared: “Did she forget her other kids?”

However, the entrepreneur had the support of some fans.

“Rocky is the only child they had together. So yes, both of them are just Rocky's biological parents. The other children belong to either just Kourtney or just Travis, not both. How difficult is it to understand that? My goodness, well [judgy] for no reason!' someone interfered.
