Go get 'em! Kaley Cuoco made her first formal appearance since her split with Ryan Sweeting was confirmed on Friday, Sept. 25. Looking amazing in a black mini, she walked the red carpet at the Longines International Races Gala on Oct. 1 in Los Angeles.

The Big Bang Theory actress, 29, put on a brave face as she posed for cameras in a flattering black sheath dress by Giambattista Valli with dramatic sleeves, paired with a matching shoulder bag and minimalist Tom Ford shoes. 

Posting a pic of her outfit on Instagram, Cuoco wrote, "I had a lovely time at the #longines gala last night! #littleblackdress." She also thanked her makeup artist, Kayleen McAdams, and hair stylist, Derek-Peter Williams, in the sweet caption.

The frock's convenient pockets hid her ring finger from photographers, but the star's rep confirmed to Us Weekly that Cuoco and Sweeting, 28, were splitting after 21 months of marriage on Friday, Sept. 25. "Kaley Cuoco and Ryan Sweeting have mutually decided to end their marriage," the statement read to Us. "They ask for privacy at this time. No further statement will be issued regarding this matter."

Before their separation announcement, Cuoco removed all photos of her tennis player ex from her various social media accounts and Sweeting disabled his Facebook page and wiped his Instagram account clean. 

The couple was last seen together on Sept. 10.
