The Paris couture shows are heating up and while Hollywood is causing a photographer frenzy at Paris's Couture Fashion Week outside with such A-listers as Diane Kruger and Cameron Diaz, some of the designs and models are heating up the runway inside.

We concentrate on lingerie and underwear in honor of a surging Madonna, who just grabbed a Grammy and will sing at the Super Bowl in the US.

The pop singer recently revealed that underwear are her favorite possessions.

The 53-year-old singer likes to look sexy for her boyfriend 24-year-old Brahim Zabrat and wears racy lingerie from underwear chain Victoria's Secret with stockings.

She was quoted earlier by the Daily Star newspaper as saying: "My favorite things in life are my fishnets and my Victoria's Secret underpants."

The 'Material Girl' star is currently preparing for the release of her 12th album 'M.D.N.A' and has dropped her exercise regime in favor of dance workouts to keep her in the best shape.

She said: "I'm not really doing Pilates any more. I'm just dancing. You know, dance aerobics. The best thing for your butt."
