CAMILA Cabello has revealed the surprising reason why her boob fell out on national TV last night.

The former Fifth Harmony singer, 25, shocked viewers of teatime staple The One Show when she accidentally flashed her nipple to millions of viewers.

And it turns out she’d been partying the night before and was still feeling a little worse for wear when the mistake happened.

Camila shed light on the gaffe when she took to her instagram stories while doing promo for her upcoming album Familia.

“Still hungover tho” she captioned the video, alongside an emoji of a tired looking face.

It was clear the video was taken either just before the wardrobe malfunction as she was wearing the same patterned shirt she wore on screen.

Meanwhile, a live feed of The One Show, with hosts Alex Jones and Jermaine Jenas and fellow guest Alan Carr, chatting away, can be heard in the background.

Camila toyed with her hair in the social media clip, clearly trying to make herself look presentable for her TV appearance.

And she almost gave her 60million followers another flash as she toyed with the necklace around the opening of her plunging blouse.

Camila left The One Show’s hosts and fans in shock as she suffered the epic wardrobe malfunction while appearing live via video link.

She was on the show to talk about her new album, when she revealed more than she bargained for.

Camila was attempting to show Alan, Alex and Jermaine her dance moves when her flimsy top fell down.

Being the professional that she is, the singer simply carried on with her routine while amending her clothes, adding: “Whoops I just flashed you.”

She tried to quickly cover up, but viewers had already seen everything.

They quickly took to Twitter, with this one saying: “I thought this was meant to be a family show! (Followed by a laughing emoji)”

Another one said: “Gotta love LIVE tv!”

While this viewer giggled: “Boobies on The One Show!”

Fellow guest on the show Alan was also left in hysterics, and could be seen clapping his hand to his mouth when Camila’s boob slip occurred.

This didn’t go unnoticed by fans with one saying: “Woops….Alan carr trying to hold it together is hilarious.”

Camila shot to fame when she was just 15 on The X Factor and came in third place with her band Fifth Harmony

After quitting the band she has since forged a successful solo career, clocking up hits like Havana, Senorita and Never Be The Same.

She also dated fellow singer Shawn Mendes from 2019 until 2021, with the pair becoming fan favourites.

They announced their split back in November, devastating those who ‘shipped’ them as a couple.

Mendes took to Instagram to inform fans about his relationship status.

“Hey guys, we’ve decided to end our romantic relationship but our love for one another as humans is stronger than ever,” Mendes wrote via Instagram story to over 64million followers.

“We started our relationship as best friends and will continue to be best friends. We so appreciate your support from the beginning and moving forward.”
