Kristen Stewart has raised eyebrows after taking a swim in a tiny white bikini that left little to the imagination, dazzling Twilight co-star Robert Pattinson, who looked like he was having the time of his life as they frolicked in the water.

The duo, who star as Bella Swan and Edward Cullen in the vampire series, have been filming scenes for “Twilight Saga: Breaking Dawn, Part I” in Brazil for the past week.

The couple was reportedly back in Los Angeles over the weekend on their way to New Orleans, La., to continue filming the movie.

The Brazil interlude was to film scenes of Bella’s and Edward’s honeymoon.

The filming cause a international stir when the couple landed in Rio de Janeiro last weekend, and periodic reports have floated out from the set.

Most recently, Kristen and Rob were spotted taking a swim.

Kristen set off fire alarms after she emerged from the water dripping wet, with the skimpy suit clinging closely to her body, revealing more than she probably wanted to.

Or maybe not. Studio Summit Entertainment has been trumpeting the racier nature of Breaking Dawn compared with the previous movies.

There have been reports that Kristen will appear near naked in the film, but will not bare enough to jeopardize its PG-13 rating, which means no frontal nudity.

Some of the filming took place at a waterfall in Paraty, then the actors and crew headed for Bag Mamangu√° in Paraty-Mirim.

That’s where the mansion is located that serves as a backdrop for the movie, the fourth installment in the Twilight series.

On Friday (Nov. 12) Pattinson and Stewart filmed the long awaited kiss between Edward and Bella a key scene in “Twilight,” “Breaking Dawn.”

The scene took place in the beach bag Mamangu√° in Paraty, Costa Verde Rio.

After kicking back for the day, Rob and crew will film in Louisiana and then return to Vancouver, Canada, where all of the Twilight films have been shot, for more filming.

Breaking Dawn, Part I, is due in theaters next year.
