Photos: Mel B's mum & sister diss her husband, Stephen Belafonte on Twitter

Andrea Brown, has hit out at her son-in-law, Stephen Belafonte in an extraordinary Twitter rant.

Andrea, who has been at loggerheads with Stephen for years, took to the social networking site to air her views - and while she may be biased in her attack, her words were fairly inflammatory. 

'Little good news 4 me lost half a stone in 1 week+ will never suffer a vile abusive 3am call from stephan Belafonti again!!' [sic] she wrote.

Soon after, she added another tweet in which she wrote, 'On average It takes 30 beatings 4 a woman to leave abusive man how sad more should b done 4 these victims!!'

The X Factor judge's husband is said to have moved to the couple's home in America, while Mel has stayed behind in their London apartment amid claims their seven year marriage is on the rocks.

Stephen is alleged to have jetted off to the US on Sunday afternoon, even before Mel had been discharged from hospital in time to return to The X Factor judging panel.

A source told The Sun: 'The fact that he left the country before she'd even gone back on X Factor is another sign of just how bad things have become between them.

While Mel's estranged mother and sister Danielle, 26, waited to hear more information about Mel's health ahead of the show on Sunday, they took to Twitter with a desperate plea. 

Danielle fell out with Mel over her concerns about the former Spice Girl singer's husband Stephen Belafonte.

She launched a Twitter tirade calling for Stephen, Mel's fellow X Factor judge Simon Cowell and even her PR firm, to get in touch with the family about her condition. 

Danielle began by retweeting her mother Andrea's message and adding a few words of her own. 

'@ANDREA_m_BROWN: Mothers worse nightmare to hear ur daughters seriously Ill in hosp and not know where to go!!' It's just horrific!!!!!!,' it read.
