Grant and Firth in bidding war
Hugh Grant and Oscar winner Colin Firth reignited their on-screen rivalry as they had a real-life battle over Bridget Jones.
The actors fuelled a bidding war at a charity auction for a walk-on part in the next movie about the bumbling singleton, created by writer Helen Fielding.
Their competing bids helped to push the price of the part up to £55,000, paid by an unnamed bidder.
Hugh - who played Bridget's bad boy former boss and ex-lover Daniel Cleaver in the romantic comedies starring Renee Zellweger - put in an opening bid for the part of £10,000 prior to the auction.
The auction was to raise money for broadcaster Mariella Frostrup's new GREAT Initiative, which she launched with a glamorous party and dinner at the Corinthia Hotel London.
And Colin, who arrived straight from shooting new film Gambit on location at Heathrow with Cameron Diaz, began bidding for the part - despite already reprising his role as Bridget's love interest Mark Darcy in the film.
Hugh was not present but called in to continue pushing up the bids until the winning price was reached.
He and Colin famously duelled on screen over Bridget.
The GREAT Initiative, which stands for Gender Rights and Equality Action Trust, is aiming to create greater gender equality in developing countries. Among its patrons is star Renee.
Mariella said she was grateful to the actress for accompanying her on a visit to Liberia "to visit the first African country with a female president and see first-hand what an amazing difference it was making".
