The 35-year-old singer, who prefers to wear outfits which are open across the top, said flaunting shoulders are sexier, reported Contactmusic.
"You see me wearing dresses that are open across the top. That area shows grace because it's dainty, but it also shows strength. I think shoulders are sexier than cleavage," she said.
The former Pussycat Doll believes in herself by staying in shape but explained it is all in her mind.
"Staying in shape is where I get my power from. It keeps my temple strong. Physically it helps because you feel more confident in your clothes and how you hold yourself, but it's a mental for me.
