Naomi Campbell has admitted that she almost self-destructed from her use of cocaine.

Campbell tells Diane Sawyer on ABC’s “Primetime Live” (to air at 10 EST Thursday night) that she’s glad she recovered, but acknowledges it’s still difficult.

“It was a rebellion in a certain way, you know?” the British supermodel says. “I don’t want to be in that pain again. I don’t want to be in that place.”

Campbell, 34, says she first tried cocaine when she was 24 but stopped before “something would have happened. Some self-destructive thing.”

“I never did drugs before I would go on the runway because I knew that’s when I was an active addict. I knew that they could see my eyes,” she says.

Campbell says she assumes others knew of her addiction at the time. “People aren’t stupid. … You think people don’t know, but they know. They know. I mean, that’s your mind playing tricks on you.”

In 2004, Campbell won her appeal in a privacy case against a London newspaper that published photographs of her leaving a drug counseling meeting in 2001. Her lawyer said Campbell hadn’t objected to the Daily Mirror’s reporting that she had a drug problem and that she had misled the media about it, but only to its publication of details of her treatment.

In the “Primetime Live” interview, Campbell also discusses some of the more glamorous aspects of her life, including a reported romance with R&B singer Usher, though she says the two were never a couple.

“We’re still friends,” Campbell says. “We were never boyfriend/girlfriend. … One of the reasons why I felt like I needed to pull back is because it was getting misconstrued.”

Spanish actress Penelope Cruz is headed down the aisle – and not with Salma Hayek.

Despite rumors of a love affair between the two actresses, a report by said Cruz gave boyfriend actor Matthew McConaughey a big “yes” when he popped the question a few weeks ago.

The couple, who met last year while working together on the film Sahara, are planning a private July wedding in Madrid.

Cruz’s last beau was three years ago – Tom Cruise, then-newly divorced from Nicole Kidman – while McConaughey has been linked on-and-off to actress Sandra Bullock.

As for Cruise, the “Collateral” and “The Last Samurai” star was recently spotted in London with Colombian model and variety-show host Sofia Vergara.

The pair met at a party in L.A. earlier this month and have become “inseparable.” Cruise surprised folks at the party when he arrived with Cruz and left with Vergara, whose nickname in the Spanish tabloids is “Sofia Viagra,” thanks to her curvaceous body.
