Katy Perry may not be wearing a bikini anymore ... but that's not stopping her from showing off one of her most famous assets.
The singer stepped out to promote "Katy Perry: Part of Me 3D" last night at the Fasano Hotel in Brazil, where she proudly put her cleavage on display in a revealing, bright yellow cut-out dress.
While Perry's known for rocking her famous curves both on stage and on the red carpet, we gotta say this may be one of her sexiest looks yet.
What do you think of the ensemble? And see how she's highlighted her cleavage before in the gallery above.
