Sarah Harding says she won't talk about Girls Aloud on Celebrity Big Brother 2017.
The singer is widely expected to enter CBB this evening as part of the new summer line up, but won't blab about her bandmates.
It follows claims that Cheryl was 'worried' about what Sarah might say in the house.
But Sarah told OK! Magazine: "I don't know what she [Cheryl] would be worried about, but at the end of the day, if I went in there, I wouldn't talk about the band."
She added this week: "I'm a loyal friend and I'm not going to go in there and talk about what's gone on.
"We were like sisters at the end of the day, so I wouldn't go in there to talk about the band, or their secrets."
Celebrity Big Brother is set to be the latest reality show for Sarah, who previously appeared on BBC One's Tumble and Channel 4's The Jump.
Although not officially confirmed for the show, Sarah was spotted yesterday arriving at the house so it'd be a huge shock if she's not on the line up tonight.
Tipped to join Sarah in tomorrow night's launch are YouTuber Trisha Paytas, X Factor's Amelia Lily, Gogglebox’s Sandi Bogle, TV psychic Derek Acorah and Absolutely Fabulous star Helen Lederer.
More rumoured Celebrity Big Brother 2017 housemates are Ex On The Beach star Jemma Lucy, Made In Chelsea's Sam Thompson, Mob Wives' star Marissa Jade and daughter of Chris de Burgh and model Rosanna Davison.
But there has reportedly been some last minute changes to the cast after some celebs dropped out.
We'll know for sure who's a part of the show this summer tonight.
Celebrity Big Brother 2017 launches on Tuesday, August 1 at 9PM on Channel 5.
