A few weeks after giving birth to her daughter Ethel Lily headed out for a posh bite to eat at the Wolsley in London. She then tweeted her horror when her breasts started to leak in public!
"I left the house without breast pads and started leaking all over myself at the #Wolsley. Oh and I wiped out in the street earlier #glam" tweeted the new mum.
She then hit back at a fan on the social networking site who called her tweet "disgusting" by firing back:
"What do you mean it's BEAUTIFUL !!!!! Boobs are not just #sexyfunbags, they be feeding implements too."
The clearly besotted mum then chatted to journalist and columnist Caitlin Moran, joking her "let down reflex" was about 10 ft!
We're loving Lily's realistic tweets about motherhood. See how other celeb mums got on with becoming parents with our round-up below...
