Sarah Harding got drunk in the Celebrity Big Brother 2017 house tonight - before BITING Amelia Lily.
In this evening's episode, Sarah got tipsy in the hot tub as she stripped down to her underwear and jumped in.
Paul Danan encouraged her to 'do a Loose Women' and go topless, but a confused Sarah just thought he was calling her loose.
The Girls Aloud star then got playful with Amelia and decided to BITE her leg.
Big Brother called Amelia to the Diary Room to check she was okay.
"I'm fine, it was a playful thing, she didn't do anything wrong. I love her, it was class," Amelia insisted.
Earlier in the show, Sarah had been reminiscing with Amelia about their days on tour together.
It all began when Sarah, Sam, Jemma and Amelia were in the living area comparing ages.
Amelia told them, “I knew I was gonna be the baby in here” and Sarah replied, “you must have only been 18 when you came on tour with us.”
Amelia went onto say, “If I could relive anything in my career, it would be your tour. I had the best time.”
Sam asked Sarah what her top moment was when Girls Aloud were at the height of their fame and she revealed, “Probably the Brit Awards. But then when we met the Queen as well at the Royal Variety.
"I’ve got one more, at Wembley Stadium supporting Jay Z and Coldplay.”
Speaking about Chris Martin, Sarah told them “he always said he’d like to write us a song back in the early days.”
Celebrity Big Brother 2017 continues nightly on Channel 5.
The latest episode airs at 9PM on Monday night while the first eviction takes place live on Tuesday.
Amelia, Sarah, Sandi, Jemma, Marissa, Chad, Jordan, Karthik and Trisha are currently up for eviction as things stand.
