GWYNETH PALTROW - PALTROW AND MARTIN'S MARRIAGE IN TROUBLE

GWYNETH PALTROW's marriage to British rocker CHRIS MARTIN is on the rocks after only 14-months - the pressure of combining their successful careers, marriage and parenthood is tearing them apart.

The couple have shared a series of blazing rows as they spend more and more time apart - the COLDPLAY singer has been working on his band's highly anticipated but delayed third album, while the OSCAR-winning actress has been left at home in London looking after their eight-month-old daughter APPLE.

A friend tells British newspaper the DAILY MIRROR, "Adjusting to married life, then being parents and now trying to sort out their professional lives has been a lot more difficult and complicated than either of them imagined."

Tensions between Paltrow and the YELLOW frontman recently boiled over at New York restaurant Next Door at Nobu - which has a no reservation policy - as they waited for a table.

The row only came to a close when the SHAKESPEARE IN LOVE beauty stormed out and waited in their car - but Martin defiantly waited for a table.

An onlooker says, "The argument began about the table, but turned into more personal things."

The couple will be spending the next weeks apart as Paltrow films new movie RUNNING WITH SCISSORS in Los Angeles while Martin puts the finishing touches on the new Coldplay album in London.
