Catherine Zeta-Jones is to be one of the presenters at next month's Tony Awards.

The 41-year-old star - who, at last year's ceremony, was named Best Leading Actress for her role in Broadway musical 'A Little Night Music' - will hand out one of the prizes at the prestigious event at New York's Beacon Theatre on June 12.

Other stars who will be presenting awards include Daniel Radcliffe, Whoopi Goldberg, Chris Rock, Alec Baldwin, Samuel L. Jackson and Kelsey Grammer.

The awards - which will be hosted by 'How I Met Your Mother' star Neil Patrick Harris - will be one of Catherine's first official public appearances since she announced last month she had been to rehab to receive treatment Bipolar II disorder, which is also known as manic depression.

At last year's awards, after she was named Best Leading Actress, Catherine took to the stage to give a gushing speech, which included an intimate tribute to her husband Michael Douglas.

She told the audience: "See that man there? He's a movie star and I get to sleep with him every night."

However, she later admitted her comments her "crass", saying: "It wasn't the most elegant thing to say, was it? I was so caught up in the moment I don't think I knew what I was saying. I had no control what was coming out of my mouth.

"Standing up there I felt speechless but obviously I said something but it was such a surprise that my brain didn't really connect to my mouth.

"What I said about Michael was heartfelt. Although thinking about it now I can't believe I said something as crass as that."
