She often raised eyebrows by wearing risque outfits during her time in the Black Eyed Peas.
And no doubt her legion of male fans will think she looked just purr-fect after posting a picture of herself dressed as a leopard on the internet.
It seems she was giving her 476,000 band of followers on Twitter a sneak preview of what she will bear wearing for Halloween.

She posted a link to the risque photo, and said: ‘Getting excited 4 Halloween! HEEeeRE naughty kitty kitty, HEEeeRE naughty kitty kitty.’
Fergie certainly looked as good as ever in the revealing outfit, which seemed to have been made from skintight latex.
No doubt her Transformers actor husband Josh Duhamel will be smiling ear-to-ear when he sees the delightfully racy photograph.
The dynamic duo hit the headlines again after they opened their hearts about cheating claims that rocked their marriage on Oprah’s Next Chapter.
Stronger than ever: Josh and Fergie recently revealed cheating claims only improved their marriage
The rumours he had an affair with a stripper hit the headlines nine months after they tied the knot on January 10, 2009, but they say the ordeal has made them stronger.
Fergie said: ‘We went to therapy. The whole thing just became a positive for us … Our marriage today, I couldn’t ask for anything more.’
Josh, who admitted visiting the strip club but denied the cheating claims, also said he was delighted that they were presented with such a difficult challenge later in the interview.
He said: ‘Now, I’m actually happy that all that happened, because we wouldn’t be as strong as we are now.
‘As much anger as a carried about it before, I’m actually thankful that it did happen, because in a lot of ways it made me straighten my ass out.’
