Kourtney Kardashian Goes Topless For NSFW Travis Barker Birthday Post -- And Fans Are UPSET?!

Kourtney Kardashian is wishing Travis Barker a happy birthday — but fans are less than impressed.

On Tuesday, the new mother took to Instagram to share some sweet words for the Blink-182 drummer on his special day. She wrote:

Awww! But it isn’t the words that have tongues wagging! It was the photos!

The Lemme founder included a carousel of steamy maternity pics from before the pair welcomed Rocky, in which the lovebirds posed shirtless in denim. In one pic, Kourt wrapped her arms around the tattooed drummer while showing off a bit of side boob, while another showed them both facing the cameras with Travis covering the 44-year-old’s chest with his hands — totally channeling Janet Jackson’s iconic topless ’90s Rolling Stones cover.

HAWT!!! But it seems like after fans began theorizing that the 48-year-old was “controlling” over Kourtney, they just don’t care to see any updates on him.

In the comments, critics slammed the photoshoot, saying things like:

Other fans say they feel bad for the spouses’ older children, as they will “eventually” see the pics:

Kourt, of course, shares Mason, 13, Penelope, 11, and Reign, 8, with ex Scott Disick, while Travis shares Landon, 20, Alabama, 17, and stepdaughter Atiana, 24, with ex-wife Shanna Moakler. Half these kids are all over social media themselves, so we’re guessing this isn’t as shocking as fans think. Though we’d guess they aren’t fans of the PDA either! LOLz!

But some fans just didn’t care for the photoshoot overall, saying:

Yikes. People really didn’t hold back…

There were plenty of supporters, though! Some fans wrote more positive comments like:

What do YOU think of the pics,
