Reese Witherspoon, the star of the film Legally Blonde 2: Red, White and Blonde, attended the UK première of the film in London on Wednesday.
Witherspoon arrived with husband Ryan Phillipe
The film, the sequel to the 2001 film Legally Blond, has already proved to be a hit in the US.
The film sees Witherspoon, 27, continue her role as the apparently vacuous Elle Woods, travelling to Washington to protest at animal testing.
The première took place at the Warner West End at London's Leicester Square.
The traditional red carpet used for premières was replaced with one in pink - Elle's favourite colour.
The after-show party will be held at London's famous luxury store Harvey Nichols, with manicurists and make-up artists attending to guests.
The film follows the huge success of the first Legally Blonde movie, in which Elle becomes a law student at Harvard in a bid to make her ambitious ex-boyfriend jealous.
The sequel took over $39m (£25m) in its first five days in the US box office charts, taking second place to Terminator 3: Rise of the Machines.
The film is currently at number seven in the US film charts, and has so far taken $75m (£48m) in the US.
It will be released in the UK on 1 August.
Witherspoon is already in the UK, filming a new version of Vanity Fair, also starring Jim Broadbent, Gabriel Byrne and Rhys Ifans.
The actress is seven months pregnant with her second child by fellow actor Ryan Phillippe. The couple already have a daughter, Ava, who is three.
