For a while it seemed that Katy Perry and Rihanna were joined at the hip, but due to clashing work schedules and RiRi's apparently never-ending Diamonds World Tour the bessies haven't enjoyed much quality time together lately. That is until the Barbadian singer accompanied Perry as she celebrated the release of her fourth studio album, Prism, in New York last night where the pair were photographed looking very happy to be reunited. Rihanna, who wore a simple t-shirt and jeans combo shared a photo of herself sitting on Katy's knee along with the caption, 'She. X She. #KatyAnna #RIHunited' - we love that they've got their own take on a Brangelina-style amalgamated moniker!
Meanwhile Cara's fans, siblings and friends took to Instagram to wish her a happy 21st birthday yesterday. Mary Charteris said, 'Happy birthday my sweet amigo @caradelevingne. The big 21. Can't believe I've known you since you were only 15. Love you long time', while Cara's big sister Poppy added, 'Happy 21st Birthday to the love of my life @caradelevingne #keepdancingbaby I'm so proud of you it's unreal.' The model herself shared a fan-made collage featuring images of her eyes and tattoos and gushed, 'Thank you to everyone especially my Delevingners for making my birthday so special!! Stay weird and wonderful forever and always.'
And finally, Elle Fanning has joined her sister Dakota on Instagram. The younger Fanning revealed a photo of herself in a leopard hat as she exclaimed 'Hello Instagram World'.
