We can only speculate but these pictures are sure to start a lot of rumors. Lohan was pictured wearing the same blue and white bikini on July 4, 2006 that she wore in the Hamptons a little over a year ago but she definitely fills out the top (wink, wink) a bit more nowadays. Check out the pics, on the left, the pics from July 4th and the right, from May 2005 and decide for yourself. Lohan has said that her breasts are back because she is healthy so is this just nature taking its course?
