GWYNETH PALTROW - GWYNETH PALTROW LASHES OUT AT BOYFRIEND CHRIS MARTIN

Stunning actress GWYNETH PALTROW has lashed out at boyfriend CHRIS MARTIN - throwing doubt on their marriage plans.

The pair, who secretly got engaged last month (March 03), were together at the COLDPLAY singer's end-of-tour party in London when Gwyneth rowed with the YELLOW star after he refused to escort her home.

THE WORLD OF TOMORROW star is said to be unhappy and insecure about the fact that Chris has not yet given her an engagement ring.

A source says, "Gwyneth was escorted in by seven bodyguards but soon after they arrived she said she wanted to leave. Things got worse between them as the evening progressed and they tried to resolve things in the VIP area downstairs."

Another guest adds, "Gwyneth was very upset and close to tears. She shouted something at Chris and rushed out. She was in such a hurry she ended up pushing into a couple of other guests."
