Rapper said to have had a huge row with the singer
It is claimed the singer told police the rapper threatened her at their home in Dollis Hill, London.
‘A huge row kicked off,’ a source tells The Sun.
The alleged argument is said to have taken place because Harvey, 29, stayed out all night.
He is believed to have received a caution from officers on Monday.
Harvey left his wife, Strictly Come Dancing winner Alesha Dixon, for Javine, 26.
She gave birth to their daughter Angel in February.
Both were unavailable for comment.
