A new body trend is gaining traction among celebrities and might singlehandedly replace the thigh gap.

Though the thigh gap — the space that appears between a woman’s thighs — was heavily criticized when it became a popular phenomenon, it seems like the ab crack — the crease that appears down the middle of a woman’s body — has taken its place. (SLIDESHOW: Thigh Gap Thursday)
Several famous models have displayed their own ab crack on Instagram recently.
At least one outlet dubbed it “the new six pack.”
The new trend already has a slew of critics, of course.
Move over #ThighGap, the latest in ridiculous trending "Beauty Standards" is the "Ab Crack"? Nothing sounds beautiful about that! #lol

Poor women always held to impossible standards #abcrack really? I know I haven't had abs since 2003 and they ain't coming back either!

According to the media, having an "ab crack" means you're malnourished. It's a natural thing. I have it and I'm far from malnourished.

Ew. Gross. An ab crack is not a thing! It means you're undernourished and have no muscle mass! NO! https://t.co/CmNrn8hu3Y
