Brown, 29, was released without charge today after being arrested in Paris on suspicion of rape.
A post on the musician’s Instagram page appeared to condemn the allegations by stating “B**** Lyin”.
It is not known if Brown was behind the post, but it gathered around 700,000 likes before it was deleted.
The Beckhams’ two boys, Cruz, and Romeo, both appeared to ‘like’ the post – and it sparked a backlash among fans.
One slammed the family for failing to keep an eye on their offspring.
They wrote: “You’d sort of think the Beckhams, as media-trained and controlled as they are, would give their son – who they put in the public eye fgs – some basic tips.”
Another added of Romeo also liking the post: “Romeo’s my fave and this is disappointing.”
Brown was released by cops in Paris today after being held following an investigation into an alleged rape at Le Mandarin Oriental hotel, where he’s was staying for Paris Fashion Week.
A 24-year-old woman claimed he raped her in his five-star hotel room between January 15 and 16 this year.
A total of three men, including the rapper, had been held over the alleged incident.
The woman filed a complaint to police, who opened an investigation. She cannot be named for legal reasons.
