Eagle-eyed Kendall Jenner sends Hailey Bieber fans into a frenzy after spotting subtle detail in pregnant model's selfies

Kendall Jenner may have just spilled the beans on Hailey Bieber's latest Rhode Skin release after leaving a cheeky comment under one of her friend's posts.

This week, the pregnant beauty brand founder posted a series of snaps, one of which included a selfie of her wearing a small strawberry sticker on her forehead. 

The strawberry design may have looked a bit familiar to some, as Bieber, 27, sent customers a sheet of the stickers when they ordered her strawberry glaze Peptide Lip Treatment upon its release last summer. 

But the one that she was sporting in her Instagram post was much smaller, with Jenner pointing out in the comments: 'R these rhode pimple patches or am I tripping?'

Her observation sent Rhode fans into a tizzy, as they enthusiastically replied to The Kardashians star, 28. 

In a new series of snaps, Hailey Bieber posted a picture of herself wearing a strawberry sticker on her forehead - which Kendall Jenner believes may be a part of her latest Rhode Skin drop 

Jenner commented on the photo, writing, 'R these rhode pimple patches or am i tripping?'

'ABSOLUTELY,' one user wrote.

Another agreed, 'Omgeeeee good catch @haileybieber can I place an order.'

'Right?! Kendall thinking what I was thinking!!!!' someone else chimed in.

One more person even seconded, 'The design is TOO CUTE TY KENNY FOR SAYING LMAO.' 

Bieber herself even replied to Jenner, leaving her with a cheeky string of side-eye emojis.

Jenner and Bieber have been friends for more than a decade, and even 'sealed' their friendship by molding a pot to the shape of their bodies during a pottery class earlier this year.

The pals posted the adorable moment on their Instagram stories.

'Friendship sealed @haileybieber,' Jenner captioned the video at the time.

Jenner was even featured as a guest on Bieber's YouTube series, What's In My Kitchen?, and taught her friend how to make a layered dip

Bieber is also close with Jenner's younger sister, Kylie Jenner, 26 - who she has apparently been turning to for parenting advice, according to Us Weekly.

Jenner is mom to daughter Stormi, 6, and son Aire, 2, who she shares with ex Travis Scott. 

Bieber announced her first pregnancy earlier this month in an adorable Instagram video post with her 30-year-old husband, Justin Bieber. 

The clip showed the two of them renewing their vows in Hawaii, as they hugged and kissed each other. 

The videographer then zoomed in on her stomach, showing that she was expecting. 

Bieber wore a skintight, long-sleeved white lace dress that came with a matching head scarf to debut her bump to the world.

In another picture that she included in the post, Bieber cradled her belly, as her husband appeared behind the camera. 

Bieber is rumored to be about six months along.  

And, in her latest series of Instagram snaps, Bieber also made a sweet reference to her growing belly. 

'Little cherry blossoms on my nails little cherry blossom in my belly,' Bieber captioned the post, nodding to her pregnancy - and her nails, which featured tiny cherry blossoms painted on them.
