Jada: Tom's like a brother

Jada Pinkett Smith says she looks upon sex symbol Tom Cruise as a big brother.

The wife of Hollywood star Will Smith says that Tom had been incredibly protective of her while they were shooting their new film 'Collateral'. She added that the actor "took care of the team" by ordering large amounts of coffee and hot chocolate every day.

The 32-year-old actress went on to reveal the secret to her happy marriage with Will Smith. Rule number one is to be completely honest with each other and ruthlessly tell the truth. "Second," she said, "it's really important to also be your partner's best friend."

The star said she doesn't believe a relationship can rest on passion and sexual attraction alone.

"At some point that fire cools off," she said.
