Britney Spears is out, Posh Spice is in — as a lyric for the Lady in the Lake in the Broadway musical "Monty Python's Spamalot."

Asked why the lyric was changed in the song "Diva's Lament," "Spamalot" author Eric Idle said Tuesday in an e-mail:

"Because we don't laugh at sad people. Mike Nichols (the show's director) requested it and he's right. We changed the lyrics in London, on tour, on Broadway and in Las Vegas. We think that it's now too sad. Britney Spears is being tortured to death and we don't want to be on that side."

The changes went into the various companies last week.

Victoria Beckham was dubbed Posh Spice when she sang as part of the Spice Girls.

What the Lady in the Lake (currently played on Broadway by Hannah Waddingham) once sang:

"I am sick of my career

Always stuck in second gear

Up to here with frustration and with fears

I've no Grammy no rewards

I've no Tony Awards

I'm constantly replaced by Britney Spears

Britney Spears!"

It's been replaced by:

"My love life is a mess

I've got constant PMS

My career is about as hot as ice

They hate me there backstage

They say I'm too old for my age

They're trying to replace me with Posh Spice

With Posh Spice!!"
