It looks like music superstar Rihanna is feeling blue these days…We’re talking about her hair! The gorgeous singer was spotted in New York City recently sporting a high-standing topknot kissed with electric blue “highlights” interwoven on a full-bodied bun. RiRi opted to keep her coif’s base sleek (with the help of hair pins) while her topknot was fluffed to perfection—all the better to show off those cobalt streaks. Score a similar look quickly with the help of colorful clip-ins. Easy peasy!
