The Simpson clan looks closer than ever.

While Jessica Simpson and husband Eric Johnson have been heating up their Mexico vacation, Jessica's mom, Tina, posted a new photo with her son-in-law on Monday, striking a pose you don't often see between family members.

Talk about one close-knit family. However, some commenters took issue with the shot of Eric's head in between Tina's legs, using words like "creepy," "weird," and even "inappropriate" to describe the photo.

But maybe we should all just give the two a break! Tina also posted a photo with her other son-in-law, Ashlee Simpson's husband, Evan Ross, with the sweet caption, "Blessed by the 2 best son in laws!!!"

Not to mention, the Simpson mama turned 56 on Monday, which is likely the reason the family was on vacation enjoying some fun in the sun. An eyewitness told ET it looked to be an enjoyable and relaxing time.

Meanwhile, this isn't the first time the Simpsons have raised eyebrows on Instagram!
