Lindsay Lohan went in for the kill -- and sucked the life out of her current boytoy, British hunk-lebrity Calum Best, while on vacation in the Caribbean this weekend. Just when you thought it was safe to go in the water!

The lip-locked lovers turned up the heat by canoodling in the ocean and basking under the red hot Bahamian sun. Let's hope they used protection!

While her new film "Georgia Rule" bombed at the box office, Linds was on Paradise Island celebrating the opening of The Cove resort at the Atlantis Hotel. The moral of the story: When life gives you lemons -- get out of the country and party!
