Shame, Naomi Campbell! The anger-prone supermodel was supposed to present at the celebratory bash for Nelson Mandela's 90th birthday in London this week, but the man himself has relegated her to a spectator role after her latest arrest for assault. Her third.

The man Naomi refers to as her 'honorary grandfather' denied her perky ass as not only was he less than impressed by her behaviour in the Heathrow fracas, the model was also wearing a 46664 baseball cap. That's Mandela's old prisoner number and the name of his AIDS awareness campaign. Maybe all publicity really isn't good publicity.

You may wonder, like I did, what on earth Pussycat Doll Nicole Scherzinger was doing at Mandela's birthday bash. I don't think Nelson wishes his girlfriend was hot like her. And I can't imagine what she'd be making conversation about with Bob Geldof, Gordon Brown, Elton John, Denzel Washington and Bill Clinton. Okay, we can probably all imagine what Bill Clinton would like to say to her! But the mystery was solved when she walked in on the arm of F1 racer and all-round British hero Lewis Hamilton.

Solange! Every time I type that word I think of a weird body part, like the webbing between your fingers or the bone at the top of your arse crack. Yes, I know it's a coccyx. Perhaps we could start a campaign to rename the uvula the solange?

"I'm sorry, I won't be able to make it in to work today. The doctor says I've an inflamed Solange."

Anyway, The Forgotten Knowles has a new album out and was let out of the house for this year's BET Awards in LA. Damn! It looks like Tina Knowles expanded her 'fashion' (and I use the word loosely!) empire to include things of a wiggy nature; and thought she'd experiment on Solange before they graced the blessed head of her cash cow, Beyonce.

It looks like Tina put some shine serum on a bunch of seaweed she found by the seashore and hey presto! Solange was ready to go. If she shakes her head to vigorously a few sand crabs might fly out. Probably a refreshingly different kind of crabs than the Hollywood crowd would be used to when Paris Hilton's about.

On the subject of Beyonce, Barack Obama admitted to the love the potential First daughters, his kids Malia and Sasha, have for Ms Knowles.

In an interview with Rolling Stone Obama also admitted that Stevie Wonder is his musical hero, and that his iPod contains "everything from Holwin' Wolf to Yo-Yo Ma to Sheryl Crow."

The Big O (oh no, that's Oprah! Scratch that) also has a lot of respect for Beyonce's hubby Jay-Z, calling him "a brilliant talent and a good guy." Brilliant in business? Wealthy? A glamorous young wife? If Obama's still looking for a Vice Presidential candidate he could have met his match made in heaven, no?

Obama's iPod tunes are better than many you'll find in celebrity playlists for sale on the iTunes site. From James Blunt liking Beck's ‘Loser' (hee) to Beyonce name checking her own tune, ‘Irreplaceable', to Delta Goodrem's love of Celine Dion (gag!) and embarrassing faux pas comment on Snow Patrol's ‘Chasing Cars' (Grey's Anatomy! This is the song they play when Benny dies.")

Delta, love, I don't even watch Grey's, and even I'm sure that bloke's name was Denny.

Great, one mention of that Beyonce tune and now I'm gonna be singing ‘to the left, to the left' to myself the rest of the afternoon.

Erica Packer is the wife of Australia's second richest man, James (who, despite his fortune, still can't buy himself the luxury of looking good in a pair of Speedos). When the model-slash-failed pop singer married the media mogul last year in the South of France, their gargantuan wedding didn't leave much change out of $15m. Erica's expecting their first billionaire baby any day now, and the mother-to-be has signed up to be an ambassador for UNICEF's United Nations Children's Fund.

"Just $1.50 is the cost of medication that will protect an unborn child," she said.

The Sydney Morning Herald pointed out yesterday that if Mrs Packer convinced the husband to part with some of his $7 billion fortune, they could save more than a few babies themselves.

Time to put your money where your wealthy mouths are, you two?

I was never a Matt Damon fan until the Bourne movies, and then, hello Dolly! He always just looked so earnest, and, er, I know this sounds petty and small, but his teeth were so large and square. But the Bourne trilogy bought Matt's buffness to the big screen and I must admit I've been a bit of a fan ever since.

Take a look at these shots of the Damon filming his new movie, The Informant in Hawaii, and your soft spot for the star may well harden over slightly. In the Steven Soderbergh flick due out next year, Matt plays a corporate vice-president who informs on his own company (yawnfest!) and is rocking the appropriate nerdy side part, 80s style mo, and bulgy belly. I'll keep telling myself it's all for his craft.

And before I leave you, I'll share today's horrid gossip which sounds, to my disgust and dismay, to be true enough: ‘Mini-Me' actor Verne Troyer is the latest celeb to have a sex tape 'leaked.'

Shudder.
