From Fun in the Sun to Selfies With Oprah: The Week's Cutest Candids

This week, many celebrities were in England for London Fashion Week and the BAFTA Awards, and they made sure to snap plenty of photos along the way. From Oprah's selfie with Michael Fassbender and Emma Thompson to Lupita Nyong'o's "losers selfie," a lot of the fun was happening overseas. Elsewhere, stars like Lea Michele, John Stamos, and Emmy Rossum had us yearning for Summer with gorgeous swimsuit photos, while Rihanna enjoyed "#cabinlife" in a puffy pink coat for a prebirthday bash. Some pics were more relatable, like when The Vampire Diaries stars Nina Dobrev and Kat Graham freaked out over the crazy House of Cards season two premiere, Mae Whitman and Miles Heizer got brunch, and Katy Perry fell in love with a tiny puppy.
