Twitter really is a wonderful thing. If it’s not Olympic gymnast Nastia Liukin uploading lovely photos of herself, it’s other ladies uploading photos of Larry Johnson buying big bottles of booze for buxom babes.

And score another one for the social networking application, as we get to enjoy some new pics of Bar Refaeli & other beauties showing their stuff for next year’s Sports Illustrated swimsuit issue. You’ll recall that Refaeli was the cover girl for this year’s edition. And from what we can tell from this little preview, 2010 is going to be just as titillating.

(More pics after the jump? You better believe it.)

But it wasn’t just Bar on the beach & boat - there’s also an in-depth look at this marvelous model only identified as “Rookie #1″:

The photos come courtesy of MJ Day, listed in the Twitter bio as “Senior Associate Editor at Sports Illustrated SWIMSUIT“. (Nice all-caps emphasis on “swimsuit” there.) If more photos like the ones above keep getting Tweeted, MJ’s followers will number in the thousands in no time - no doubt putting Valerie Luxe & DaJuan Summers’ little Twitter bet to shame.
