Britney Spears took the stage in Sacramento, CA, last night to kick off her Femme Fatale tour! First though, Britney got a hug and kiss from her boyfriend, Jason Trawick, in her dressing room. The show featured Britney in a variety of skimpy costumes, from sequined bikini-type pieces to denim shorts and much more. The performances will keep Britney occupied for most of the Summer with a string of California dates in June before she moves across the country in July. August will see Britney on the East Coast before she heads north for a few Canadian concerts. The start of things went well for Britney, who twittered before bed, "Can't sleep. Way too much Adrenaline right now! Sacramento was on fire tonight."
