Jessica Biel recording with Justin Timberlake

Jessica Biel has recorded an album with Justin Timberlake.

The actress was urged to enter the recording studio by her pop star boyfriend, and has worked on several songs with her in a bid to ensure his own devotees buy Jessica's music.

A source revealed: "Justin's written and produced the best part of an entire album for Jessica.

"He wants to get his own fans on side, so he's provided backing vocals on most of the tracks too."

Meanwhile, it has been revealed that the 'Blade: Trinity' actress made an embarrassing gaffe while making her new movie 'Easy Virtue' in England.

Director Stephan Elliot revealed: "We were staying in a hotel waiting for a writer and I suggested we go for a walk in the park.

"There in Hyde Park was this little Ferris wheel that they just put up for a little funfair but Jessica goes, 'Oh it's the London Eye. I thought it would be a bit bigger.'

"She had no f**king idea whatsoever."
