Holmes hardest working actress: Judy Greer

New York, Dec 3 (IANS) Actress Judy Greer is impressed by "Dead Accounts" co-star actress Katie Holmes. She thinks Holmes is the most hard working actress.

''Katie is one of the hardest-working actresses I have ever worked with. She cares so much. She works so hard. She's early to rehearsal and the last person to leave," contactmusic.com quoted Greer as saying.

The 33-year-old actress split from actor Tom Cruise in June after six years of marriage with whom she shares six-year-old daughter Suri.

''I have just been impressed by her work ethic, honestly and her ability as a single mom, to juggle being an awesome mom. I can barely schedule in a workout and getting to rehearsal, and I'm just here by myself in an apartment. It's small.

"She's like got a kid, she works out every day, she's cooking dinner at night for her daughter, she manages to go and get her a new dress if she has a special thing, going to her lessons after school . . . it's pretty impressive. She's pretty impressive. I've rarely seen her without a giant cup of coffee in her hand, I will say that," said Greer.
