A smiling Katie was glowing after peforming in Broadway play Dead Accounts which sees her share a passionate kiss with one of her co-stars. She was presented with flowers during curtain call during which she was roundly applauded.
No doubt Katie will be hoping the buzz surrounding her performance will add a much needed boost to her acting career, which appeared to stall during her marriage to Hollywood superstar, 50-year-old Tom Cruise.
The pair, who are parents to six-year-old daughter Suri, split in June with Holmes filing for divorce amid speculation she was growing increasingly unhappy with the role Scientology -- Cruise's religion -- was playing in her daughter's life.
Sources close to the former couple said they were determined to keep things amicable for the sake of their young daughter.
While Katie enjoys her run on Broadway, Suri has reportedly travelled to London to be with her father where he is currently shooting All You Need Is Kill.
Other stars who pursued theatre when their love lives were shattered include actress Sienna Miller who took to the London stage after her then boyfriend Jude Law's fling with his children's nanny was exposed in 2005.
Madonna made her Broadway debut in 1987 shortly after her marriage to actor Sean Penn failed.
And Ethan Hawke took to the stage after his marriage to Uma Thurman ended in 2003.
