By now you have probably heard that stars are now venturing into the art world. Actors, singers, and big names in many different industries are buying art and even participating in their own creative projects. This week's gallery of Instagram pictures is indicative of that trend. This week we have James Franco, Tobey Maguire, Swizz Beatz, Carmelo Anthony, Milla Jovovich, Kendrick Lamar, Mos Def, and even art inspired by Kanye West. Of course, we also have photos capturing major figures and events in the art world like Ai Weiwei's Time cover, the Venice Biennale, KAWS' new work, Liu Bolin's latest project, and Tino Sehgal's winning performance piece. There's a lot to see, which is why we are very sure you'll love flipping through The Best Artist Instagrams of the Week.
