The 28-year-old is frequently pictured with her nipples visible beneath thin shirts while out and about in Los Angeles. Her unsupported bust has created a media frenzy and her father Jamie, who has a conservatorship that gives him legal control over his daughter’s personal and business affairs, has reportedly decided to put a stop to it. Jamie was charged with getting Britney`s life back on track after she suffered an emotional meltdown in 2008, during which she publicly shaved her head and didn`t sleep for days. He has helped her turn her life around, but is concerned her repeated failure to wear underwear is sending the wrong message, and could reverse all his hard work. "Jamie`s control over Britney`s life is incredible," an insider said. "He hates the pictures of her with her nipples all over the place so he has banned her from leaving the house without a bra. He wants her to put across the right impression." Jamie has even threatened to fire any member of Britney`s staff who lets her out of her home without the appropriate underwear. "One security guard was told he is close to getting fired because he lets her go out without her bra. He treats Britney like a child, but he means it all for the best," the source added to British newspaper The Sun.
