NEW YORK (CBSANewYork) — Tonight the 58th Annual GRAMMYs will air on CBS and that means all eyes will be on the stars — how they look and what they wear.

But what some people don’t realize is that celebrities have their own secrets to looking good, CBS2’s Jill Nicolini reported.

From celebrities like Taylor Swift, Lady Gaga and Adele — how do these ladies get their “Red Carpet ready” look?

Beauty expert Jeanette Zinno says celebrities will go to extremes.

“They do everything from teeth whitening, cosmetic procedures, hair extensions,” Zinno said.

Celebrities like Gwen Stefani go from short do’s to long locks with ease thanks to hair extensions. Individual protein tipped strands are bonded to your hair and instantly can give you fuller, longer hair — and even can add some color.

Celebrities can pay anywhere from $1,500 to $3,000 for the extensions, Zinno said.

There’s also something called the “Hour Glass Treatment,” meant to help celebrities fit into skin-tight dresses. First you apply a series of gels consisting of essential oils, caffeine and algae to the legs, stomach and thighs.

“Then you’re wrapped up in saran wrap,” Zinno said. “There is a lot of hot and cold thermal technology going on. “You can lose 1-3 inches, which is amazing.”

Also your smile is one of the first things that people notice. According to Dr. Lana Rozenberg, for around $250, superficial stains can be removed.

“We isolate the teeth and the gum and apply two different gel applications. In about five minutes time you are ready to go,” Rozenberg said.

Dr. Rozenberg also says a great way to instantly make your teeth appear brighter is to mix a little silver eye shadow into your lip gloss and then you’ll get those beautiful Hollywood pearly whites.
