Lily Allen's husband is embarrassed that she wrote her new single about him.

The 28-year-old singer recently released her new track "L8 CMMR," which features lyrics such as "My lover/Shoots and scores like he's Maradonna/Undercover, under the covers/ My man is a bad mother*****," which refers to her love life with husband Sam Cooper but she claims he wasn't too happy when he heard it.

"Sam was completely embarrassed," she said.

The outspoken star has also admitted that she's no longer interested in engaging in feuds with other pop stars and says she want to focus on exploring different issues through her music: "I'm still curious and still want to dig deeper about things. I have a lot of questions to be answered. I don't really care about bitching about Katy Perry. To me that was never my edge. That was just sensationalist s***."

Lily - who has two-year-old daughter Ethel and 10-month-old Marnie with her husband Sam - has guest edited a special issue of Shortlist magazine titled "How to Be a Man, By Women," which will be available on Thursday.
