Kim Kardashian allegedly stopped boyfriend Kanye West from enjoying a dinner with music colleague Jay-Z.

The 'Keeping Up With The Kardashians' star is said to have called time on meal out in London recently when she wanted to leave, taking the 'I'm So Cold' rapper with her.

The 34-year-old producer apparently upped and left the capital city's Zuma restaurant - where Beyonce Knowles' husband had hired out a section - as soon as Kim gave him the cue.

A source told The Sun: ''Jay expected Kay and Kim to mingle.

''But as soon as Kim whispered in Kanye's ear, they left.''

'99 Problems' lyricist Jay-Z and Kanye are in town to perform in five collaborative concerts.

Meanwhile Kim, 31, has used the opportunity to promote her self-titled fragrance in Britain.

The couple was up early this week for a Radio 1 interview, then attended the Fifi Awards where her signature perfume was nominated for the Best Celebrity fragrance award.

However, the reality star's scent lost out to pop star Justin Bieber's 'Someday'.

During their stay Jay-Z is planning a star-studded party to celebrate his manager's 40th birthday.

Rob Kardashian and his singer girlfriend Rita Ora, plus Gwyneth Paltrow, Rihanna and Beyonce are amongst celebrities on the guest list.
