Sadly, you'd be mistaken - in between all the bikini-flaunting and boy-enticing going on at the Polaroid Beach House yesterday, Lindsay and her sister Ali suffered a near-heart attack when they thought their younger brother Cody had been swallowed up by the sea! Apparently Lindsay lost sight of her bro for a moment and, when she turned back, couldn't see him anywhere. Fortunately, Cody was quickly spotted a ways off from shore and, after quickly reading the lil' hellraiser the riot act behind some surfboards, the festivities were able to resume in short enough order. Whew!

Note: we're reusing our video of Lindsay's party from this morning since it captures the whole incident. We're guessing that it probably makes a little more sense now!
