GOOD Morning America Fans have pointed out a surprising detail about both Robin Roberts and Sam Champion from their joint segment on Thursday.

The meteorologist, 61, has admitted the incident was a complete accident, but it’s one that viewers said they are very happy about.

On Thursday, Sam and Robin took a moment out of their segment to joke around about the meteorologist’s “ego.”

The 61-year-old joked around about having a “poor ego,” but Robin didn’t buy it and mocked him by sarcastically crying like a baby.

“Wahhhhh,” she sang out, as her face scrunched up.

Sam immediately started laughing and his laughter only grew after Robin teased: “Call the wahh-mbulance!”

Robin quickly returned to a straight face as Sam got the segment back on track, telling fans they’ll be seeing more of his co-star on GMA in “just moments.”

It wasn’t the teasing that fans noticed, as they’re used to the duo’s hilarious relationship, but the stars’ outfits choices instead.

One viewer shared a clip of the segment, in which Robin wears a light-and-dark-blue dress and Sam wears a suit look with the same colors.

“Love the outfits – planned or not,” the social media user captioned the video.

Sam re-shared the segment snipped and admitted: “Oh wow!!!  I didn’t notice til now!!”

Other fans quickly jumped in to share their excitement over the morning show pair’s matching outfits.

One Twitter user wrote: “You got the memo to color coordinate this morning.”

A second insisted: “Great minds think alike!!!”

Another tweeted: “Two of my most favorite NY people looking awesome in blue.”

The GMA stars and good friends are all about the sarcastic banter during their on-air segments, often taking turns teasing one another.

Earlier this month, Sam mocked Robin over a sultry voice she was forced to use temporarily.

“I’m not trying to be sexy, Sam,” the host insisted while chatting with the meteorologist live on air.

“But these allergies…oh my goodness,” Robin added while talking about how much they affect her.

Sam couldn’t help give his colleague a little light teasing.

“You were doing a little ‘hey,'” Sam quipped, mimicking Robin as though he were using a sultry voice, too.

Robin also mentioned her allergies and had a similar voice during her chat with her glam team that morning.

She captioned her morning message video: “Good morning! #GlamFam & I hope you had a wonderful weekend.

“Not going to let a bout with my allergies keep me from sharing a little #MondayMotivation with you. #cmon”

One fan told her in the comments: “Totally understand as I have allergies, too!”

Another commented: “I share this pain this morning…ooof.”
