After working together on tracks like the recent 'FourFiveSeconds', the musicians looked pleased to see each other on Monday morning (9 March).
Kanye arrived for the show in a seriously gorgeous black Porsche, before leaping out to greet Sir Paul and pose for a few photos.
The rapper was also pictured giving Paul's wife Nancy Shevall a hug and a kiss on the cheek. Kanye's own wife, Kim Kardashian West, didn't appear to be at the show.
The group then headed inside for Paul's daughter Stella's show.
Kanye and Sir Paul have been working together on several tracks recently include the Rihanna song 'FourFiveSeconds'. They've also collaborated on 'All Day' and 'Only One', the latter of which is a tribute to Kanye's daughter North West from the eyes of his late mother Donda.
Other big names in attendance at the event included Vogue's Anna Wintour and model Cara Delevingne, who was taking a breather from walking the Fashion Week catwalks herself.
