Since then, fans have copied the track and posted it online,
much to the annoyance of bosses at Allen's EMI record label.
Apologizing for the blunder on her MySpace blog, Allen has revealed
that she recorded the cover song 'a stripped-down, piano-backed
version of Spears' synth-heavy original' because she loves Britney.
"[It's] simple, really. I love Britney and I love the song," People
quoted Allen as writing in her blog.
The singer, whose sophomore album 'It's Not Me, It's You' is due out in February, added: "Mark Ronson asked me for something no one had heard to play on his radio show and 'Womanizer' was the only song I had as an attachment on my BlackBerry and I couldn't get home to send him anything else in time. I had asked [Mark] to talk all over it so it wouldn't get ripped, but he didn't, thanks Mark for getting me in serious trouble with my record company."
