After the very successful comeback of the Pop Princess Britney Spears, she is now in the course of claiming her fifth number one album in America as her Circus album is currently threatening Kanye West's reign on the Billboard chart to just a week span of time. If strong sales continue and the Toxic singer does rocket to the top of the U.S. album chart next week (10Dec08), she'll join the likes of Barbra Streisand, Madonna and Janet Jackson among the ladies who have scored more than four number ones. Well, let's hope Britney will continue living the life straight forward.
