Lily Allen's Saucy Quip Shame

Singer Lily Allen was left red-faced after she made a saucy quip about another singer without realising her microphone was on.

The pop star was judging acts on British TV program "Talent Show Unsigned" - when she took a shine to the frontman of band The Revenue.

She said to pals, "He's fit. I would f**k him!" - but was stunned when she was told her microphone was still on.

Single Allen split from her long-term love Seb Chew earlier this year.
