She was pictured flashing her bra under a sheer black blouse earlier this week.
And it seem Britney Spears favours the risque look.
The 32-year-old flashed her white bra under a see-through lace cream top as she went shopping in West Hollywood on Wednesday
The Circus singer paired the frilly blouse with lace trim over dark blue jeans, and a pair of brown platform wedge heels emblazoned with gold spikes.
The blonde bombshell shielded her eyes with a pair of reflective pink sunglasses, and styled her hair in a messy bun.
Britney has been taking most of January off, as she gears up for the second leg of her Las Vegas Piece Of Me residency, which kicks off January 29.
Contrary to what people might expect after a long and illustrious career in the entertainment industry, performing isn't a walk in the park for her, as she explained in a revealing new E! documentary, I Am Britney Jean, which aired in December
The Womanizer singer opened up about the disparity between her stage act and the real her.
'I have always been kind of shy, since I was a little girl. It’s who I am to be modest, so I really can’t help it,' Britney said.
Known for her outlandish stage acts and erotic videos the Outrageous singer said she has to step out of herself to play the role: 'It’s almost like it’s my alter ego when I get on stage.
'I turn into this different person seriously. Bipolar disorder,' remarked the star, who famously shaved her head and crumbled under the pressure of fame in 2007.
The performer claimed she gets her anxious streak from her father.
'Backstage I catch myself doing the same hand mannerisms as him and worrying and I'm like "Oh my god I’m turning into my f***ing father right now. This is horrible."'
The documentary chronicles the Toxic star in the frantic four month preparation for her ambitious two-year Las Vegas residency at Planet Hollywood.
