She is known for flaunting her famous curves wherever she goes. And Amber Rose did just that as she promoted a new push-up bra on her Instagram account on Saturday.

The model slash actress, 34, made tongues wag as she posted a video of herself showing followers how to apply the new stick-on intimate wear.

The video shows Amber pulling two strings that tighten up the bra, which do a fantastic job of highlighting the siren's generous cleavage. She then pulls up a backless PVC dress that she had around her waist, showing fans that the bra is perfect for any ensemble- while also being completely strapless.

Amber captioned the video: '#ad My fav season? I don’t have to think about it… with my girls? And my @sneakyvaunt? It’s gotta be push-up season.

'The former love interest of rapper Wiz Khalifa continued: 'Oh, is it your fav too? Well rosebuds, it will be, ‘cause you know muva has got a hook up for you - they’re giving up to 25% off all bras at sneakyvaunt.com.'

'Amber ended: 'Get your order in girls, and f*** just walking into the holiday party, make a statement. 'While wearing a platinum blonde wig, the sexy siren ends the video by turning around showing off her perky behind.
