It's the most unlikely friendship in pop music since SIR PAUL McCARTNEY and Rupert The Bear.
DAPPY, FAZER and TULISA met legendary rockers ANTHONY KIEDIS, FLEA, CHAD SMITH and JOSH KLINGHOFFER in an LA studio last week.
They had passed each other in the corridor where they are both beavering away on new material.
Eventually wideboy Dappy introduced himself to frontman Anthony.
He even invited them to listen to some of N-Dubz' songs – and amazingly the Chilis agreed.
Fazer said: "We're big fans of them so it was very cool to meet them. They just happened to be in the next studio to us, so we had to say hello.
"Our trip to the US has been jam-packed. We've been recording late into the night every day but managed one day off to have fun. We can't wait to share the tracks we've been recording with everyone."
A lot of wannabes and bigwigs are on a charm offensive at the Oscars this weekend.
But none of them are as efficient as the Camden scamps at social climbing.
They befriended PRINCE CHARLES at The Royal Variety Show last year but rock royalty is far more impressive.
It's a big coup for Dubz credibility. Def Jam bosses reckon they have a big future in America and pals like the Chilis will be very handy. They have sold 60million records globally and could teach them a few things about being rock stars.
It's a miracle Anthony is still alive. Although he is teetotal now, his antics used to make Hollywood hellraiser CHARLIE SHEEN look like a nun.
The US group are finishing up their tenth studio album while N-Dubz are close to completing their debut album for the States.
The Chilis' working title is Dr Johnny Skinz's Disproportionately Rambunctious Polar Express Machine-head - inspired by a friend's trips on acid.
Perhaps Dappy will now draw on his misadventures on Meow Meow...
