Mel said she is happily married with Stephen and even plans on having a baby with him this year but they have been seeing a therapist.
The 35–year-old, who has been married to Belafonte for three years, told British Reveal magazine: 'I am happily married, me and my husband are far from getting divorced, we're very tight.
'Stephen and I have been seeing a family therapist for the past four years - normally once a week.'
She added: 'On my reality show, you do see me cry during one of the sessions.'
Brown is confident their marriage is going well as she says the pair are planning on having a baby of their own.
Melanie added: 'Between me and Stephen we have three girls – Angel's nearly four, his daughter Giselle is six and Phoenix is 11.
'We want a baby together and plan on having one in the next year.'
The star's reality show, Mel B: It's A Scary World, airs in the UK on Monday 11 October.
