Mary-Kate Olsen and her boyfriend Nate Lowman continue to enjoy the parties and galleries of Art Basel Miami, last night stopping at the Delano hotel. On Tuesday, it was Nate's show the two cozied up at, but last night was more about a lovefest with Mary-Kate. I'm an Olsen sucker for sure, but so sweet! MK has always been an artistic one, but as a designer and photography coffee table book writer, she's even more one of the creative crowd. Not sure if we'll ever get to see MK lounging poolside in her bikini with her artist man, but it seems the couple is heating up Miami just the same.
