In this week's A-List Insider:

Scott Disick checks into rehab, Gisele Bundchen is retiring from modelling and Kanye West is heading to Glastonbury.

Scott Disick enters rehab

Scott Disick aka Kim Kardashian's brother-in-law has entered a rehab facility in Costa Rica to battle his alcohol addiction.

The reality star, who is married to Kourtney Kardashian, is said to have sought profession help after a weekend of heavy drinking in Atlantic City.

"I realise my issues are bigger than me and I'm ready to truly remedy this struggle I continue to battle," he said in a statement.

The stint in rehab comes just months after he passed out and was rushed to hospital during an episode of Kourtney and Khloe Take The Hamptons.

We wish him all the best.

Gisele Bundchen to leave the catwalk

And over in fashion, supermodel Gisele Bundchen is reportedly preparing to walk the catwalk for the last time after dominating the runway for over 10 years.

The 34-year-old beauty, who is the world's highest-paid model, will apparently bow out professionally at Sao Paulo's Fashion Week next month in her native Brazil.

Brazilian news website reports that although the mother-of-two will no longer appear on the catwalk she will still model for high profile fashion spreads and campaigns.

During her career, the former Victoria's Secret Angel has fronted campaigns for H&M, Chanel and Carolina Herrera.

Yeezus at Glastonbury

And finally Kanye West has been announced as the headline act for this year's Glastonbury.

The rapper is set to take to the stage at Worthy Farm, Somerset on Saturday, 27 June. But guess what, some people are not happy.

One disgruntled fan has started a petition calling for him to be banned and it had already amassed nearly 1,000 signatures at the time of writing.

Apparently Kim Kardashian's husband is "An insult to music fans all over the world."

Remember in 2008 when Jay-Z came on the stage singing Oasis's Wonderwall after fans complained about his headline slot? Wonder how West is going to handle this backlash? I've got feeling he's preparing one of his epic rants right now.
