Love is in the air for Elizabeth Olsen! The actress is dating [1] indie singer Robbie Arnett, E! News confirms. The couple first sparked dating rumors in February when they met while on vacation in Mexico, and according to a source, Robbie is a "great guy." "They are in an exclusive relationship and Lizzie is excited about him. She deserves it. It's very new though, but they seem to like each other a lot already," the insider added. Just a day ago, Elizabeth was all smiles while walking arm in arm with the musician in NYC. Elizabeth famously called off her engagement [2] to actor Boyd Holbrook in January 2015 after nearly three years of dating.
