The 38-year-old singer let slip in 2013 that she was originally supposed to front the band in the early 2000s before Fergie had even joined the group.

And now the band is back recording new material, Nicole has apparently been secretly recording a new club anthem with Will.i.am, Fergie, apl.de.ap and Taboo and was spotted with the quartet at Metropolis Studios in London on Monday (26.09.16).

A source told The Sun newspaper: "Nicole met all four band members and was laying down vocals until the early hours. She was singing about 'feeling the fire' and 'wanting her way like a holiday'.

"Taboo and APL went into the recording booth to do their bit first, then Will and Nicole went in before she went back in with Fergie.

"It was a very different direction for Nic compared to the sloppy ballads on her last two album flops."

Nicole is believed to have drawn on her relationship with new beau and tennis star Grigor Dimitrov for musical inspiration, proving she's finally over long-term boyfriend Lewis Hamilton, who she split from last year.

The source added: "She's over her heartbreak with Lewis Hamilton and that showed. It's a massive dancefloor filler."

They were reportedly in the studio until 2am to finish recording. Nicole then left in a car whilst the Black Eyed Peas went on to Soho's Cirque Le Soir club to celebrate the session.

will.i.am and Nicole have a close bond as he helped her become a member of the Pussycat Dolls.

Nicole went on to have a solo career after the Pussycat Dolls disbanded in 2010, releasing a solo album 'Killer Love' which featured her number one hit 'Don't Hold Your Breath'.
