Jessica Simpson in racism row

Jessica Simpson has sparked a race row.

The singer-and-actress outraged the Native American community by using a racial stereotype in an interview.

When asked if she would take back the expensive speedboat she bought for her now ex-boyfriend Tony Romo, Jessica reportedly told gossip website TMZ: "I'm not an Indian giver."

The phrase refers to someone who gives a gift and then takes it back. It is said to be based on the stereotype that Native American people are untrustworthy.

But Jacqueline L. Pata, executive director of the National Congress of American Indians, has defended Jessica, claiming many people did not understand the racist meaning of the term.

She said: "Most people flippantly use the comment 'Indian giver' without realising its true meaning. Jessica's comment provides us with a good chance to educate people not to stereotype Native Americans by using a comment that is both incorrect in the way most people use it, and culturally insensitive to Native people."

Meanwhile, Jessica has reportedly been "devastated" by claims Tony was having an "emotional affair" with another woman in the months before the couple split.

Jessica reportedly introduced Tony to Natalie Smith backstage at one of her concerts in February and Tony has been accused of sending the girl "flirty texts" since.

A friend of Natalie's said: "Natalie and Tony are not officially dating, but they are having an intimate relationship."

There has been speculation Jessica - who was dumped by Tony earlier this month - would turn to former husband Nick Lachey for support, but Nick has denied he is planning to rekindle his romance with her.

Jessica's former boyfriend John Mayer has also insisted he would "never" consider reuniting with the blonde beauty.
