So, for those of you who don't know; former Girls Aloud member, Sarah Harding, is currently ensconced within the four walls of the Celebrity Big Brother house.
And when compared to previous Celebrity Big Brother contestants, Sarah has a relatively high profile, so it's no real surprise that Twitter has devoted time to analysing the singer's every move since she made her grand entrance this week.
What was it like being in Girls Aloud? Has she had surgery? And, perhaps most importantly, does she hate Cheryl?
Unsurprisingly, it's been a mixed bag so far, with some members of the public keen to support the 35-year-old performer and others…well… less so.
Here's the breakdown:
