Catherine Zeta-Jones flashed her breasts to theatre-goers last week.

The Welsh actress - who has children Dylan, nine, and Carys, six, with husband Michael Douglas - stunned the audience of her play 'A Little Night Music' on New York's Broadway when she opened her kimono a little too much, revealing her breasts to the left side of the audience.

Critics have not been kind to Catherine for her portrayal of 19th century Swede Desiree in the production, with one blasting her for not being able to sing and act at the same time.

The 40-year-old star recently admitted she is "insecure" about her appearance.

She said: "I have many insecurities. I'm a lot more reserved and quiet than I let on to be.

"I think I'm not aesthetically beautiful. I have a broken nose here. I had a tracheotomy when I was a kid. I had broken capillaries. I always ask my husband, 'Do I look fat in this dress?' Can you see that spot on my face?' "
