Chipmunk: Saturdays need more edge
Chipmunk has said he thinks The Saturdays "need more edge".
The grime star, 19, has hooked up with the girl band and is hoping to revamp their sound.
He told the Daily Star: "I'm going to be writing for them, giving them beats and verses. They need more edge and I'm on it."
But the Oopsy Daisy singer added that, apart from his work with the band, he wants to take a break from collaborations - because he thinks they're "boring".
He has recorded with N-Dubz and has also featured Dutch singer Esmee Denters on his latest track Until You Were Gone.
But he said: "I'll probably leave all the collaborations for now and concentrate on my own thing - it's all got a bit boring."
