Spotted!: Jennifer Lopez was all smiles backstage of Cirque Du Soleil’s “O” in Las Vegas at Bellagio’s theatre on January 19, 2012. The singer looked casual in a cream knit sweater and distressed jeans but glammed the look up with high heeled booties and lots of accessories including a jeweled headband which has been the accessory of choice among celebrities lately. Shop for a large selection of headbands ranging from $10-78 at Nordstroms.
