London: Singer Lily Allen suffered an allergic reaction after she painted herself green to dress up as an alien for a Halloween event.
The 28-year-old has got rashes on her skin, reports femalefirst.co.uk.
"It's Saturday night and I've had a bad reaction to the green paint from Halloween, my face is covered in hives," Allen posted on her Twitter handle.
