Pete and Kate Bust Up over Lily
And it's all reportedly down to a touch of the green-eyed monster...
An insider told the Daily Mirror that Kate found a present Lily had given to Pete last year, and went "ballistic".
Said the source: "(She) kept shouting about why he had kept the thing from Lily all these months. Pete insisted she was being paranoid, they were just mates.
"But Kate was having none of it and said there was no way Pete was going to the Brits if Lily was going - especially as she wasn't going herself. Pete was gutted as he was looking forward to it."
MTV.co.uk were the first to report that Pete and Lily buried the hatchet at last summer's 'Get Loaded In The Park' festival and the two have kept in touch ever since.
However it seems their budding friendship might have to be put on hold if Mossy has anything to do with it.
"Kate feels that because of her non-music background, she'll never be truly on (Pete's) wavelength," explained the source.
Time to start learning the recorder, Kate?
