The Girls Aloud singer, 35, bared her intimate area at the Cosmopolitan Ultimate Women of the Year Awards back in 2013.
Wearing a skin coloured gown with a very daring slit, Sarah flashed the flesh to paparazzi as she walked to the event.
Luckily for the Loving Kind singer, she wasn’t “doing a Britney” and exposed a very prim pair of nude coloured panties.
She wasn’t so lucky with underwear when she performed at the Bryn Terfel Faenil Festival in Bangor back in 2007, where an energetic performance saw both her nipples fall out while live on stage.
Viewers of Channel 5’s Celebrity Big Brother saw Sarah bare her soul swell as her flesh, as she experienced a rollercoaster ride of emotions in the famous house – and that’s putting it mildly.
After a boozy night saw Sarah strip off and bite X Factor finalist Amelia Lily on the leg, she broke down in the Diary Room, claiming she hadn’t meant to drink while in the house.
Her erratic behaviour lead to CBB bosses putting her under 24 hour surveillance to monitor her health – but that didn’t stop evicted housemate Jordan Davies accuse her of stealing bottles of wine.
But things improved for Sarah after she struck up a relationship with fellow housemate and Bachelorette hunk Chad Johnson.

The pair annoyed housemates after they shared a series of saucy snogs and embarked on under the cover antics on the communal bedroom.
But although Sarah described him as “her rock” to host Emma Willis upon leaving the Borehamwood mansion, Chad is distinctly absent in pictures of the wrap party.
Sarah was spotted hand-in-hand with a mystery hunk, while Chad cosied up to arch-nemesis Jemma for an Instagram snap in the back of a cab.
Are Chad and Sarah over before they’ve even started?
