It’s been another busy week for the A-list, with Halloween providing the perfect excuse for posting more pictures on the internet.
Kim Kardashian showed off her little Frozen fans, while Mariah Carey harked back to more mermaid-y days. Taylor Swift revealed one of the best celebrity fancy dress throwbacks of our times, and Alexa Chung posed for pumpkin pictures.
Naomi Campbell and Jessica Chastain both had interesting photo shoots, and Lena Dunham revealed a past sexting fail, which to be fair, is clearly a fail on the part of the recipient.
See all the delights from the week in our gallery, below.
Fan of the Dirty Martini, Gwyneth Paltrow?
I think there's been a misunderstanding.. Or has there?!? #amfAR #inspirationgala
Lady Gaga gets jazzed about the amfAR Inspiration Gala
Thank you VALENTINO for my beautiful blush dress. It was elegant but comfortable, made it easy to just get lost in the jazz.
... and makes a purchase for a good cause
#amfar after the auction. Got a print of Liz Taylor for a good cause. She's flipping the bird in a cropped pant with hoop earrings in front of a limousine. So basically I bought a mirror. Ha!
Someone out there recognises this Lena Dunham picture
#tbt to summer 2010 when I forced my mom to take a photo of me that I could "casually" text to the dude I liked. He didn't respond so now I'll share it with 2.1 million people. Live a little!

David Beckham pays tribute to Kirsty Howard
Words cannot describe how amazing this young lady has been over the years .. Kirsty has been defying doctors for many years and whilst doing that she has been raising millions of pounds for terminally ill children... I met Kirsty in 2002 when she became the nations and my good luck charm for the game against Greece , we also met the queen together in Manchester so you could say we have spent some amazing moments together over the years and it was an inspiration to meet such a brave young lady with so much drive for helping others.. My love and thoughts go to kirsty's parents and sisters as this inspirational young lady will be missed ... My heart and love goes to Kirsty for letting me be a small part of your world over the years.. Rest in peace
