Lily Allen can't remember who she proposed to

Lily Allen asked a rock star to marry her - but can't remember who it was.

The Fear singer called Kings of Leon brothers Caleb, Nathan and Jared Followill and their cousin Matthew to declare her love for one of them, but admits she was so drunk she has no idea which member of the group she spoke to.

Lily, who asked the group's management to call them after meeting him during her US tour, said to the mystery rocker: "I love you. I want to marry you."

Speaking about the incident, she said: "I was really drunk. We played in Boston on the same night. I wanted to see them."

It is unknown how the musician responded to the 23-year-old star's proposal.

Lily, who has been single since splitting with art dealer Jay Jopling at the beginning of this year, has previously complained that touring is bad for her sex life because it makes it harder to meet people.

She said: "It's nice to have sex with people you love. I'm not really a promiscuous person. I haven't slept with many people and on a promotional trip you don't get a chance to meet or s**g anyone and I don't like one-night stands."
