The shooting spot at St.Thomas in the US Virgin Islands had a lot of security to avoid the hot scenes between the characters, Edward Cullen and Bella Swan, from being observed.
Armed police patrolled the beach while a police launch moved around in the sea to ensure that nobody got a glimpse of the shoot, reports dailymail.co.uk.
Stewart showed off her slim frame in a bright green bikini that was unfastened at the halter, suggesting there could be a topless scene in the awaited movie too.
“Breaking Dawn” will be the fourth instalment in the hit “Twilight” franchise, based on the best selling books by Stephanie Meyer.
