Mariah Carey posted a message of support for ex husband Nick Cannon on Instagram, Sunday, defending him over "false allegations looming in the press.”

The singer did not state what the allegations against the father of her children were, however her post comes just days after Cannon hit out at the National Enquirer over a story they appear to be planning to run, alleging that Carey will be petitioning for full custody of their children because of Cannon's “erratic behaviour”.

The text image posted by Carey on Sunday read: "There's no validity to the false allegations looming in the press regarding our family. Nick is the father of my children, we will always stand up for each other, have each other's backs and we will always remain a strong family." The post was later shared by Cannon on his own account.

Last week Cannon posted an image on Instagram which stated that the Enquirer was preparing an article reporting that he’s suffered a “nervous breakdown and his erratic behaviour has given ex-wife Mariah Carey no choice but to petition for full custody of their children”.

Addressing the allegations, Cannon wrote: "MORE LIES!!! So the @enquirer wants to play around with my children. Only Evil operates in this manner. What is the purpose? Except to exemplify pure immoral wickedness.

“If you report these lies expect a slander and defamation lawsuit. Look everyone, see how the media is trying to break a King? It's all good though, I'm a warrior! I was built for this! Me and my family, my mindset, and my spirit are all stronger than ever.

“I felt like releasing this so called "journalist" info to the public so you all can get at them, but instead I release nothing but positive energy into the Universe,” Cannon’s post continued. “No weapon formed against me shall prosper! I receive help through prayer and patience! #Blessed #Awakened."
