We can't get enough of a celeb sibling. And one of our faves has to be Alexa Chung's big sis Natalie, who took to Instagram this weekend to share pics of Alexa playing the perfect aunty to her niece, Tiggy, at a family wedding. The ever-stylish Alexa donned a ruffled flamenco-inspired navy blue polka-dot dress, whilst her mini-me niece sported a matching sky blue polka dot neckerchief. The cuteness levels are almost too much! But not quite. Natalie also treated us to Alexa making the most of the Scottish weather and getting all Wuthering Heights on us. We love this.
Meanwhile on Instagram, Cara Delevingne got a cheeky peck from new BFF Zoe Kravitz, and modelled a Lolawolf (Zoe's uber cool band) cap, whilst BFFs Anna Dello Russo and Giovanna Battaglia gave us a touch of the green-eyed monster, with some glorious pics in sunny Capri with Dolce & Gabbana. The pair showcased their bikini swimsuit bodies with a series of impressive synchronised swimming shots before donning their best Dolce florals for some perfect boat snaps. Never mind 'a touch of the green-eyed monster', we actually couldn't be more jealous.
Elsewhere, the newly-weds of Instagram were on top form. Olivia Palermo and Johannes Huebl showed us exactly how to do newly-wed chic (smug smiles and matching poses compulsary), whilst Cheryl Cole shared those rings with a casual blue jean and turquoise court shoe combo. It's making us feel very warm and fuzzy inside.
