The pregnant pop star woke up this morning feeling like the aquatic species of bird - which is known for only being able to move slowly on land - because of her ever-expanding baby bump, but her penguin dilemma led her to start thinking about the chocolate biscuit that shares its name with the animal.
She wrote on her twitter page: "I feel like a penguin, not the chocolate covered biscuity kind, but an actual penguin that waddles - now can`t stop thinking about chocolatey penguins doh! (sic)."
Lily - who got married to Sam Cooper earlier this summer - is starting to feel the effects of pregnancy as she enters her third trimester.
In a twitter post on Sunday (21.08.11), she wrote: "I can`t see my toes and I`m not bendy anymore."
Since tying the knot in June, Lily and Sam have been living in domestic bliss at their country home in Cranham, Gloucestershire, South West England.
The 26-year-old singer has even been learning how to knit and sew, previously saying: "I`m being taught how to knit. I`m so not rock `n` roll anymore. I`m embroidering too. I`m actually in the process of making cushions."
