This week in the world of celebrity social media, some of our favorite snap-happy stars were definitely working and playing hard, and sharing it all with their fans and followers. Gwyneth Paltrow jumped for joy in a snakeskin-print Stella McCartney bikini, and Emma Watson paid a visit to Vogue's NYC offices. Karlie Kloss drank a cup of coffee while underwater (don't ask us how or why), while Brad Goreski spent the day styling his new client, Fruitvale Station star Melonie Diaz. Lindsay Lohan and Alessandra Ambrosio both hung out with athletes this week — Lindsay got a lift from Shaquille O'Neal while Alessandra shot a Funny or Die video with Clippers player DeAndre Jordan. Lake Bell embraced her inner cowgirl during a trip to Texas as Paris Hilton wore a printed bikini in Ibiza, and Hayden Panettiere proved she was a girl after our own hearts when she shared a snap while munching on french fries.
