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.
The "Not fair" singer dressed like an alien to attend the 2013 United Nations Children's Fund (Unicef) Britain's Halloween Ball here. She performed at the event with singer Robbie Williams to help raise funds.
