ON a list of people you wouldn't want turning up at your house in the small hours, bad boy Chris Brown would be some-where near the top.
The US singer is better known for his conviction for thumping his then girlfriend Rihanna in 2009 than he is for his mediocre music career.
But he raised eyebrows instead of fists at the weekend as he turned up with a hefty entourage at Adele's West London home and didn't take his leave until the early hours.
A source close to Adele said: "It was all a bit cloak and dagger. He arrived in the middle of the night and didn't leave until around 2am.
"He arrived in huge, blacked-out cars, with plenty of muscle surrounding him."
Go Crazy singer Brown is a pal of Adele's rumoured love interest, Brit rapper Skepta, and first met her at the 2013. They were pictured at the bash hitting it off, as Hello singer Adele appeared to be giving him a little piece of her mind.
At the time, Brown tweeted: "Pleasure to meet you, Adele. I heard your words and that's all that matters. Thank you for speaking truth."
That encounter came four years after Brown was found guilty of assaulting Rihanna and as a result banned from visiting the UK.
But despite that ban, he was spotted last week in Mayfair restaurant mys.
He also posted on Instagram a shot of him with on-off model girlfriend Ammika Harris and their son Aeko, which fans guessed was taken in London.
I'm just surprised at Adele. As an outspoken advocate for women's rights, you would expect her to be keeping better company.
At the Brit Awards in 2016, she publicly supported US singer Kesha after she alleged she had suffered abuse at the hands of producer Dr Luke.
