Michael Jackson's mother Katherine has reservations about her granddaughter's acting career as she is convinced the King of Pop would not have wanted Paris to pursue a career in entertainment at such a young age.

The late Thriller icon's 14-year-old daughter is desperate to be an actress and will make her big screen debut in the 2013 fantasy film Lundon's Bridge and The Three Keys.

However, Katherine, Paris's legal guardian, admits she was reluctant to let the youngster chase her Hollywood dream.

"I'm pleased and concerned (for Paris) at the same time because I don't think that Michael would have wanted her to be out there this soon. But she wanted it so badly," she told US talk show host Piers Morgan.

''She kept saying, 'Please, Grandma! I want this, you know'. It was something she really wanted so I just gave in and said OK.

"I said, 'How do you know you can act? You haven't had acting (experience)'. So I started sending her to acting (classes). Before then she said, 'Just try me, just try me. I can cry on cue'. She showed me how she can cry. She's very good."

Michael, who was just a boy when he shot to fame in The Jackson 5, went to great lengths to shield his three children from the spotlight, covering their faces with masks and blankets when they stepped out in public.
