The 39-year-old former Spice Girls star hit headlines earlier this month, when she was admitted to a medical centre for treatment for a "serious" ailment, reported People magazine.
"I'm very good was very polly but much better now and for the record my hubby never would lay a hand on me sorry took so long but any response fuels rumours #lovemyfamily #lovemyfans," she posted on Instagram.
On Christmas Day, Mel B also posted a shot that showed her and her kids with Belafonte, 39.
Mel B has been married to Belafonte since 2007.
