Judge Marsha Revel sentenced LiLo after an incredulous prosecutor, Danette Meyers, told the judge that Lohan has been thumbing her nose at the court.

The evidence was loud and clear today -- Lindsay violated probation by failing to attend her alcohol ed classes based on the schedule set by the judge. There were lots of excuses, but ultimately they didn't fly.

The judge said there was a pattern of violations since Lindsay was placed on probation in 2007 following her plea bargain in her DUI case.

Lindsay broke down as she addressed the court, telling the judge, "I did the best I could."

Lindsay dissolved into tears when the judge imposed the sentence.

Lohan must surrender on July 20 in Judge Revel's court.

UPDATE: Sheriff's spokesperson Steve Whitmore just explained ... generally, a female inmate in Lindsay's situation only serves 25% of their sentence ... which means LiLo will most likely spend 25 days behind bars.

53 seconds -- that's exactly how long Lindsay Lohan was able to beg for mercy in open court before she started to break down and cry.

Judge Marsha Revel allowed Lohan to address the court just moments ago -- and in between teary-eyed breakdowns ... Lindsay apologized multiple times and tried to explain why she missed alcohol education classes.

So we gotta ask ...

Lindsay Lohan's lawyer -- Shawn Chapman Holley -- threw everything but the kitchen sink at prosecutor Danette Meyers today to try and keep LiLo out of jail ... and now it's your chance to fire off the objections for her!!!!!

It's simple ... just grab a hold of your mouse ... aim ... and fire away!!!!

This latest Michael Jackson auction has a unique twist -- the owner of the items says he got them from MJ himself ... by trading other memorabilia with the King of Pop.

The auction -- set for October 6-15, 2010 -- features several crazy MJ items, including a custom Swarovski crystal jacket and the gloves MJ wore on the cover of "Bad." Those two items, along with one of MJ's jackets, came directly from Michael.

Ed Kosinski, part owner of Gotta Have It!, tells us he actually traded MJ for the stuff. He says Michael had a thing for "Our Gang," Charlie Chaplin, Shirley Temple, Elizabeth Taylor, and other vintage Hollywood items.

The auction also features signed photos and authentic MJ lyric sheets.

Mark-Paul Gosselaar's divorce was the most predictable thing on the planet -- because months before the "Saved by the Bell" star filed for divorce, he sold off the L.A. house he shared with his wife.

The 3,296 sq. ft. home in a swanky planned community has two bedrooms and two baths -- and based on our calculations, that means one bedroom for Zack ... and one bedroom for his wife.

According to the deed transfer docs -- obtained by TMZ -- Gosselaar and his estranged lady-partner signed over the deed to another couple back in March ... three months before the actor filed for divorce.

Here's to hoping the new owners have better luck than the old ones.

In 1984, John Cafferty and the Beaver Brown Band hit #1 with the song "On the Dark Side" from the film "Eddie & the Cruisers." Guess what he looks like now!
