Mel B is said to be devastated over tweets posted by her sister Danielle saying that she fears for the former Spice Girl’s mental state

Danielle questioned whether or not Mel B was lying about some strange tweets allegedly sent out by a hacker from Mel’s account, talking about family members selling stories and money.

The strange tweets from Mel B's account that led to the argument

The two sisters fell out three years ago, following disagreements about Mel B’s relationship with Stephan Belafonte and this whole Twitter affair will surely put further strain on their relationship. Clearly Mel’s tweets were hacked, but Danielle was having none of it and let her older sister know exactly how she felt

Danielle is known for being a bit of an attention whore, so it’s best not to pay too much notice, we just hope they’ll be able to put their differences behind them one day.
