Celebs Swag It Up for Kentucky Derby, Tom Brady Redeems Himself

4:22 PM PT -- A stunner down in Louisville ... Maximum Security has been disqualified after a replay review of the final stretch. The second horse to cross the finish line, Country House, has now been declared the winner. MS was found to have been impeding another horse.

3:59 PM PT -- Maximum Security just won the 145th Kentucky Derby, beating out Game Winner ... which was the pre-race favorite horse to win it.

And by the looks of the race track and how far ahead MS broke out in the end, this baby loves the slop ... just eats it up.

Hollywood didn't skimp on the swank for the 2019 Kentucky Derby, including Mr. Tom Brady ... who came back in a big way after temporarily being outshined by Baker Mayfield.

Celebs were out in force Saturday at the Churchill Downs racetrack in Louisville, where much of the Patriots organization seemed to be in attendance ... not to mention some Broncos stars, like Von Miller, and other footballers from the Packers and Browns.

TB was there too, of course, and his Day 2 outfit definitely had a lot more swag than his Friday one did. You'll recall ... he was barely recognizable standing behind Baker and his pink suit.

All is well now though -- Tom looked great, as did his teammates. In fact, everyone was dressed to the nines on the day of the big race ... even the non-athletes.

Some other A-listers who showed up include Wilmer Valderama, NeNe Leakes, Backstreet Boys singers Kevin Richardson and Howie D, Joey Fatone, Stormy Daniels, Jeff Bezos, Richie Sambora ... and even Anna Nicole Smith's daughter, Dannielynn Birkhead, who wore her mom's iconic KY Derby look from 2004. Anna died of an overdose in 2007.

At the Kentucky Derby, it's always hard to figure out the best of the best-dressed. Everyone was looking fantastic, if we do say so ourselves.
