From movie premieres to the Broadway stage, the stars have been busy in the last 24 hours.

Katie Holmes was all smiles Wednesday morning when she arrived to the stage door of the Music Box Theater in New York City. The 33-year-old has been hard at work on the new play Dead Accounts, which recently opened on Broadway. The show will run through February.

Meanwhile, Amanda Seyfried looked radiant in a little black dress at the London premiere of Les Miserables. The 27-year-old actress, who plays Cosette in the big screen adaptation of Broadway classic, was joined by her co-stars Anne Hathaway, Eddie Redmayne, Hugh Jackman, Russell Crowe, Helena Bonham Carter and Sasha Baron Cohen.

Over in Canada, Mark Wahlberg touched down in Toronto for the annual Miracle Day for the CIBC. The Ted star met up with kids and employees of the equity trade floor in the Ontario city to raise money and awareness for children’s charities.

“Jail’s not a nice place; I am trying to encourage kids not to ever go there,” Wahlberg said in a press conference. “I want to make sure that I give back and provide an opportunity for kids to not make the same mistakes that I made and give them an opportunity to pursue their dreams and make things happen.”

Speaking of kids, some of Hollywood’s parents were spotted hanging out with their little ones on Wednesday.

Halle Berry and her 4-year-old daughter Nahla were out and about in West Hollywood, Calif., while Matt Damon, his wife Luciana and their girls caught a flight out of John F. Kennedy airport in New York City.

Damon’s BFF Ben Affleck and his daughter Seraphina were spotted in Brentwood, Calif., while Sarah Jessica Parker took a stroll with her daughters Tabitha and Marion on the east coast.
