Actress UMA THURMAN has secretly married her businessman beau APRAD BUSSON, according to reports.

Sources claim the couple's engagement party last month was actually a guise for their nuptials.

The Kill Bill star threw her first of two lavish parties on the grounds of Busson's Kensington, London home last month, upon announcing she was set to marry the Swiss businessman.

Then the actress insisted on sharing the news in her native America by arranging a second bash at her Manhattan apartment earlier this month. - an event reports now say was really a secret wedding celebration for the couple.

According to the New York Post, Thurman - who sparked pregnancy rumours when she was snapped with a protruding stomach while on vacation in Europe last week - is allegedly enjoying her Honeymoon on the trip with Busson.

But a spokesperson for Thurman denies the star has wed.
