Lily Allen angry that her wedding details leaked

"Oh and whoever leaked my wedding invite to the press, you're a [expletive] and your not invited anymore, have some respect and stay at home," Allen tweeted.

The card itself shows Allen and Cooper's faces pasted over those of a frumpy couple riding a tractor.

Cooper reportedly proposed to Allen, 25, on Christmas Day while the couple was vacationing in Bali.

Allen, 25, and Cooper, 32, began dating in July 2009. In August 2010, they announced that they were expecting their first child, but in November it was revealed that she lost the baby.

According to WWD, Allen met with Chanel's Karl Lagerfeld earlier this month to talk about her wedding dress.
