Lily Allen's husband was left mortified after the pop star wrote a song praising his sexual prowess.

The Smile hitmaker unveiled new track L8 Cmmr in February (14) as she teased fans with clips from her upcoming third album Sheezus.

The lyrics make references to lengthy lovemaking sessions and Allen admits the track was inspired by her husband Sam Cooper's bedroom skills, but she lied and told him it was a general "idea" because he was so embarrassed.

Allen tells Britain's Daily Telegraph, "I think he's embarrassed. He's a very shy person. He likes to go to the pub and hang out with the lads, but he's not like, 'Wahey! My wife's singing about how good I am in bed!' It's more, 'Oh God, really? Do you have to?' And I have to go, 'It's not really about you, it's just an idea.' But of course it's about him."
