In an online thread, critics claimed they had proof that the model’s butt looked smaller about a year ago.

One critic assumed: “It is surgery season.”

Another critic theorized: “Could be butt pads.”

A third critic speculated: “I think it’s the dress, but girlie might have been working out.”

A fourth person chimed: “Definitely a butt implant. Love her back dimples though.”

A commentator mockingly said: “Like we’re supposed to believe her butt just grew because she’s not 19 anymore.”

This is not the only time the supermodel showed off her bottoms.

On Saturday, Stephen Baldwin’s daughter shared a sexy snapshot of herself and her hubby.

Hailey flashed her underwear in a sheer dress.

The see-through outfit had woven black material that revealed gaping holes.

The neckline became a turtleneck as her boobs became exposed.

Hailey’s black underwear could easily be seen under the transparent top.

Standing next to his wife, Justin pouted at the camera as he showed off his scruffy chin.

The pop singer covered his head with a black beanie, wore matching shades, and had on an oversized leather jacket.

She captioned the post: “Frosty.”

In the comments section, a fan cheered: “A couple that slays together, stays together.”

Hailey’s snapshot came about as rumors swirled that the two were having marriage troubles.

Many followers noticed the pair had not been seen in public together in some time.

A source close to the couple told Radar: “He acts like a needy kid all the time, and she’s constantly having to apologize for him and try to get him to act like an adult,”

The insider also claimed that Hailey was fed up with Justin’s immature behavior.

She was reportedly embarrassed during an event they both attended for her skincare brand.

The duo celebrated their fifth wedding anniversary in September.
