Pippa Middleton's whirlwind romance with new man Nico Jackson appears to have hit a speed bump.
Now can reveal that the high-flying stockbroker, 35, wasn't happy with his 29-year-old girlfriend after discovering she'd been sending flirty texts to Prince Harry!
'Nico adores Pippa but her flirting's off the scale,' says a source.
'She often texts Harry with saucy jokes, suggesting they meet up.
'To Pippa it's just being friendly, but she told me Nico wasn't very impressed.
'They've had some big rows about it.'
Harry, who's dating Cressida Bonas, 24, will no doubt laugh it off but Pippa's now having to watch her vivacious behaviour.
Our source adds: 'Nico's asked her to tone it down.'
