Scruffy Britney Spears wears dirty trousers for a second time as she heads to a dance rehearsal

She was spotted earlier in February wearing a pair of soiled sweatpants at her local grocery shop.
And it appears Britney Spears may need to brush up on her laundry skills.
The 31-year-old was snapped yet again in a pair of dirty trousers as she made her way to a dance rehearsal on Thursday in Hidden Hills, California.

Time for a clean? Britney Spears wore dirty trousers for the second time this month as she headed to a dance studio in Hidden Hills, California

The trousers were dotted with what looked like brown patches of dirt, as if the singer had been out hiking and had taken a fall.

She wore a blue tank top and pink-and-orange Nike trainers as she walked through the studio's parking lot.
The former American X Factor judge scraped her newly dyed brunette locks into a high messy bun, and shielded her eyes with over-sized sunglasses.

The pop star carried a beige leather bag, which she held close to her chest. In need of some energy for her no doubt grueling dance session, the singer was seen holding a blue Gatorade drink.

Big change: Britney debuted her new brunette locks at Elton John's Oscar bash on Sunday night

Britney debuted her new brown hair colour, a glossy chocolate brown hue, at the Elton John AIDS foundation Oscar party on Sunday night.
The singer had been thinking about changing her look for about a month, according to her colourist, Brittany Hunter from Mark Slicker Salon.

She told E! News: ‘We wanted to make sure she was going to be committed to it before we made the change as it can be a difficult process going from light blonde to brunette.

Her natural hue: The pop star's colourist said about her new colour: 'In the end we went with a very natural and rich light brown. We wanted the right tone that would complement her skin color'

‘We started the process on Thursday and then finished it up on Sunday. We wanted to make sure the color was going to stick and it wasn't going to fade.’

Britney is known for her ever-changing tresses and went dark in 2006, 2007 and twice in 2009.

Her hair dresser continued: ‘I wanted to keep her as close to her natural color as possible, so not too dark. In the end we went with a very natural and rich light brown. We wanted the right tone that would complement her skin colour.
