She works out just about every day with a trainer. So it’s little wonder she likes to show off the results of all that cardio.

On Tuesday Britney Spears stepped out in a nearly see-through white tank top that showed off her decolletage nicely after a workout session at the Performing Arts Center in LA.

The 42-year-old singer has been keeping in top form to headline her Piece Of Me show in Las Vegas; her next performance is on Wednesday.

The Perfume hit maker appeared to be wearing a black bra underneath.

She matched the under shirt with a very short pair of hot pink shorts that showed off her toned (but not tanned) legs.

On the blonde beauty’s feet were a pair of black and pink trainers with white socks.

The Oops! I Did It Again singer also carried a cell phone that had a Minnie Mouse style hot pink polka dot cover.

Around her neck was a gold necklace with two charms – one appeared to be a snake. A gold watch that looked vintage was on her left wrist.

The ex-wife of Kevin Federline had her nails perfectly manicured with light pink polish.

The mother of two also had on a pair of mirrored sunglasses with tortoise shell frames.

She held onto a bottle of Dasani water and what looked to be a cup of ice.

With her was a body guard and she seemed to be followed by a pretty blonde woman.

Over the weekend Spears made news for letting up DJ Pauly D onto her stage at her Sin City show.

The former Jersey Shore star looked thrilled to be a part of her entourage and could not stop laughing.

Britney has been putting on shows for several weeks.

Her next is on Wednesday and she also has a performance scheduled for Valentine’s Day which falls on Saturday.

It is likely her new beau Charlie Ebersol will fly out for the show.

Will she spend Valentine’s Day with her beau?: The If U Seek Amy songbird will have to also perform on Saturday, which is Valentine’s Day, but perhaps her new boyfriend Charlie Ebersol, who she is pictured with here at the Super Bowl, will join her
