Mel B Mel B has come back to the UK for a visit.

But her arrival into London prompted a rather frightening incident.

The singer and her hubby, Stephen Belafonte, were accosted by a ranting stranger as they exited Heathrow airport.

The unwelcome episode occurred as Mel and her entourage, including her baby daughter Angel, hovered in the arrivals terminal, signing autographs.

A random man approached  the group and started verbally insulting Stephen.

"Who is he? Who is he?" he shouted at Stephen, before telling him: "Don't talk to me like you don't know me, bruv."

Becoming increasingly irate, the angry chap then turned his attention to a nearby photographer, thought to be telling him to cool down, and two came to blows with a scuffle. Mel and Stephen Belafonte

The man tried to swing a punch at the photographer, and the two ran around the airport, as Mel and co looked on.

At one point witnesses say the man made a gun gesture at Stephen's head.

The bizarre fracas came to an end when Mel B, Stephen and the rest of their group eventually headed back indoors and attracted the attention of a policeman - the man was duly arrested, as Stephen told officers he was "bananas".

However, it's credit to Mel that where most celebs would get wound up by the incident, she kept her cool - and could even be seen chuckling at certain points, apparently tickled pink by the randomness of it all.
