Kristen Stewart and Robert Pattinson took Breaking Dawn to London on Wednesday, and the pair did not disappoint, arriving in sizzling outfits.

Stewart, 21, showed up in a gorgeous Roberto Cavalli black sequined gown while Pattinson, 25, arrived in a dapper Emporio Armani suit.

The London premiere of The Twilight Saga: Breaking Dawn - Part 1 also brought out Taylor Lautner, who was also dressed in Armani. The three stars were greeted by a sea of screaming fans, complete with plenty of camera phones and giant signs that read Twilight Rocks.

On Monday, Stewart was joined by the rest of the Breaking Dawn cast for the film's Los Angeles premiere. After days of camping out in the unusual California rain, some 2,000 fans had the rare opportunity to take pictures and shake hands with the actors behind Bella Swan, Edward Cullen, Jacob Black and others.

The Twilight Saga: Breaking Dawn - Part 1 is expected to break records when it opens in theaters on Friday.

Expect 'Breaking Dawn - Part 1' to suck the life out of the box office to the tune of $150 million this weekend, box-office analyst Jeff Bock told MTV News.

In 2010, Eclipse, the most recent Twilight film, made more than $698 million at the box office worldwide.
