Ashton Kutcher, Miranda Lambert attend Kentucky Derby

(CBS/AP) Stars came out in droves for the 138th rendition of the Kentucky Derby on Saturday at Churchill Downs in Louisville, Ky.

The festive scene began as soon as the gates opened Saturday morning.

Among the stars who attended were country singers Eddy Montgomery of Montgomery Gentry, Miranda Lambert, Travis Tritt, Clay Walker and Randy Owen.

Montgomery would not reveal his Derby bet. "If I tell that, it's going to be everybody's favorite," he said.

But Walker confidently predicted I'll Have Another would reach the winner's circle.

Ashton Kutcher attended the race as well, and it seems he and Lambert have made up. Back in April, Lambert accused the "Two and a Half Men" star of mocking country music while at the ACM Awards.

From the sports world, the lineup of celebrities included New England Patriots coach Bill Belichick, Kentucky basketball players including standout Anthony Davis, Louisville basketball coach Rick Pitino, tennis players Andre Agassi and his wife, Steffi Graf, World Cup skier Lindsey Vonn and Tennessee Titans defense end Kamerion Wimbley.

Singers included Cyndi Lauper with her two sons, Mary J. Blige, Taylor Dane and Mary Wilson of The Supremes. And from Hollywood, there were Debra Messing, Lynda Carter, Quinton Aaron, Ginnifer Goodwin, Kellan Lutz, Ice-T and comedians Fred Willard and Ron White.

Miss America Laura Kaeppler also arrived as did actor Terry O'Quinn, noted for his role as "John Locke" in the television series "Lost."

When asked which horse he would bet on, O'Quinn asked: "You tell me?"

The 138th rendition of the Derby drew a record crowd of 165,307 people who crammed into the iconic track to watch the race. The huge throng beat the previous record Derby crowd of 164,858 last year.
