Britney Spears boyfriend sick of her dirty habits

Pop princess Britney Spears’ boyfriend Jason Trawick is tired of her dirty habits and has reportedly asked her to change her clothes and wash her hair more often.

The Toxic hit-maker keeps wearing the same outfit for several days and rarely cleans her hair, which has infuriated

According to reports, Trawick recently refused to go out in public with her until she took off a dirty dress.

“Britney isn’t the type to cover herself in pretty smelling lotions. She hates washing her hair, so sometimes it can smell downright sour. She’ll sometimes grab an outfit and wear it two or three times in a week,” said a source.

“Recently she put on a sundress for the third day in a row, but Jason refused to leave the house with her until she put on something else,” the source added.

The 28-year-old singer is apparently trying to mend her ways as her habits might lead to a strain in her relationship with Trawick.

“Thankfully she’s trying more now because even she knows you couldn’t think of a more embarrassing reason for a relationship to break down,” the source said.

According to friends, Spears – who was recently pictured in the same orange vest twice in the space of a few days – has always been relaxed about her appearance.

“It’s just plain laziness. She was the same when she was married to Kevin Federline,” the source added.
