DEMI Lovato’s cleavage stood to attention when she poured her curves into a sinfully tight dress.

The Sorry Not Sorry singer has been known to drop jaws with her cleavage-cramming bikini body reveals.

But Demi Lovato is now taking a different approach to the flesh-flashing game, this time flaunting her sizeable assets in a conservative-looking dress.

However, it seems that old habits die hard as the brunette bombshell sexed-up her look by parading her boobs in the plunging design.

With her two breast pals fighting for attention, the singer owned the style transformation.

No doubt keen to showcase her Jessica Rabbit figure, the body confident babe highlighted her curves as she modelled the skintight dress on her Instagram story.

Flashing a hint of leg in the midi-length number, the songstress completed her look with a sky high pair of stilettos.

Clearly a fan of the ensemble, the US talent posed for not one, but two selfies.

Eager to give fans a full look at her wardrobe choice, Demi captured her outfit in all its glory in a mirror snap.

In a second post, the starlet held the camera close to her face as she offered an up-close-and-personal glimpse at her glossy locks and immaculate makeup.

The musician has been on a roll when it comes to parading her killer assets online.

Earlier this week, she shared a picture of herself lying on a bed in silky white lingerie.

With her peachy derriere taking pride of place in the sensual bedroom exposé, Demi no doubt caused a stir among her 60 million followers.

In awe of the post, one lovestruck viewer commented: “She is such a beautiful girl. I would marry her in a heartbeat.”

Making reference to the bombshell’s perky booty, another impressed fan wrote: “Brutal!” alongside several peach emojis.
