Ashton Kutcher isn't about to let criticism for his Popchips ad or confirmation of ex-wife Demi Moore dropping his name as her Twitter handle get him down. Kutcher, 34, made an appearance on the red carpet at the elite Barnstable Brown party in Louisville on Friday night, held annually on the eve of the Kentucky Derby.

All eyes — and cameras — were on Kutcher when he arrived at the star-studded event, which was also attended by Kellan Lutz, Tom Brady, Ginnifer Goodwin, and Cyndi Lauper.

Kutcher made a new friend and patched up an old feud while celebrating the Kentucky Derby at the Barnstable Brown party, reports People. Country singer Miranda Lambert, who had previously accused Kutcher of making fun of country music when he presented her with an award at the Academy of Country Music Awards, wearing a ten-gallon hat and enormous silver belt-buckle, retracted her previous position on Twitter and posted a picture of her with Kutcher.

"Here it is y'all," Lambert tweeted. "He is sweet and lives country music! For real!:)"
