British singer-songwriter Lily Allen is feeling the pressure as her wedding day approaches. 

The 'Smile' star is set to marry her fiance Sam Cooper in June, but with just one month left until the big day she is starting to get stressed about the plans. Taking to her Twitter page this morning, May 19, she wrote about the drama and joked it would be easier to elope:

"Tip of the day: don't ever get married, its a nightmare, and everyone involved (or not as the case may be) turns into a c**t. Is there a train station for Gretna Green?"

"All fine now, said c**ts are safely back in their boxes. #itsMYwedding!!!!!!!!!"
