The pair bicker online
The tiff kicked off when mum-of-two Peaches, 24, told her followers that she’d just got a new breast bump to help her feed 5-month-old son Phaedra.
‘Thanks @Medela_UK my new Swing pump has arrived this morning and is an absolute life saver. #breastfeeding #breastisbest,’ Tweeted Peaches.
Lily, 28 – who has daughters Ethel and Marnie – quipped in reply: ‘@peaches_g @Medela_UK pumping n dumping eh ?’
‘Pumping and dumping’ refers to a method used by mums to get alcohol out of their breast milk when they’ve been drinking.
But Peaches was quick to set Lily straight over the unjustified smear and told her: ‘@lilyrosecooper Ive been pumping to increase my milk supply.Not “pumping and dumping”.
‘My son is a big feeder so I pump in between feeds too.’
This isn’t the first time that the pair have argued – in 2006, Lily said on radio that she could take Peaches in a fight.
