Lily Allen is suffering with a nasty mouth ulcer. The singer - who is currently seven months pregnant - is in some pain as she has a nasty sore right on the end of her tongue. She tweeted: I have a spiky ulcer on the end of my tongue. Her loyal followers then gave her lots of advice on how to get rid of the ulcer. One user said: gargle salt water. Another advised: oooooh painful & irritating - mouthwash of warm salty water xxx (sic) And it seems the ulcer is not Lilys only problem. She is not enjoying the current rainy British weather and has had to warm herself up with some hearty porridge. She tweeted: PORRIDGE DAY (summer is over) (sic) Last month, Lily said she felt like a penguin that waddles. The pop star woke up one 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 cant stop thinking about chocolatey penguins doh (sic). ES
