Former Spice Girl Mel B 's relationship with her younger sister Danielle Brown has been much publicised in the past, but the estranged pair appear to be more distant than ever after Danielle went on a Twitter tirade against the star.
Danielle took to the social networking site to voice concerns for her sister - who she has not seen in over three years - after the message 'die Mel B' appeared on the singer's feed.
After an exchange, in which Danielle defended the pair's upbringing and told how she was worried for Mel's mental state, the younger Brown sibling called for a "private family meeting", claiming Mel only communicates through the media.
However, Mel - who now lives in Australia hosting their version of Strictly Come Dancing, as well as appearing as a judge on The X Factor - has deleted all of her tweets, suggesting she could have been hacked.
The sisters entered into a Twitter war of words last year after Danielle accused Mel of standing her up for a meeting.
However, Mel also said then that a hacker had got into her account and arranged a meet-up with Danielle.
At the time, she tweeted: "OMG just been hacked, changing my account someone is messing with me and my family, my sister has never asked me for money. I love her to bits. I would never have a twitter argument. This is crazy I am correcting my account right now, this is freaking me out!! Password changed!! What a sick person!!"
After the whole event Danielle spoke to Star magazine about how upset she was at not having seen her famous sister for so long.
"I've not seen her for three years. I was stood up. It’s horrible," she said. "I'm appalled by her…it's so raw.
"I never would sell a story or get paid to talk about her. I don't need to make a drama about my sister to get publicity."
