Morning round-up: Lady GaGa’s ever-changing hairstyles, plus how Michael Jackson got his Balmain

Uh oh. Lady GaGa is back in London town, folks, and we really want to know how big her hair entourage is. Because following her mid-air hair make-over on the 10-hour flight to London yesterday, she then stepped out for a night on the tiles in that super-covetable hair bow of hers. Just how many looks can one girl have?

Meanwhile, the British Fashion Council has opened applications for the spring/summer 2010 Topshop New Generation sponsorship. The only requirement is that you must have been in the business for less than three years, so what's stopping you? [Catwalk Queen]

Have you been kept awake at night wondering how Michael Jackson came to get his hands on that Balmain zebra-print T-shirt? Don't be ashamed. We have, too. Turns out Jacko's got friends in high places – French Vogue's fashion director Emmanuelle Alt, who also wanted to sort out his tour outfits. Oh er. [The Imagist]

And finally, all's well that ends well for Sienna Miller. Because after US Vogue editor-in-chief Anna Wintour called her ‘toothy' after her last cover, it's been confirmed that she will be fronting the magazine for a second time in June. Fingers crossed she doesn't have anything wrong with her this time... [Independent]
