Rachel McAdams Has Her Sister Kayleen To Thank For Her Red Carpet Beauty Looks

And it's super sweet.

It's no shock that Rachel McAdams looks like a million dollars in front of every flashing camera. Her skin is flawless and her makeup is always on point. How does she do it?! Well, she's finally revealing her red carpet secret weapon...

No, it's not an expensive beauty product with miraculous powers... it's her sister, Kayleen.

The stunning Canadian sisters posed side-by-side, wearing fairy tale-like frocks from Valentino and Marchesa, for The Hollywood Reporter's annual beauty issue and Rachel couldn't help but gush about her little sister.

"Kayleen has a very calming effect on me,” the "Doctor Strange" star said. "Spending two hours with her beforehand sets me for the night."

"I like to know I can help calm you before you go out there because there’s a lot coming at you," Kayleen, a graduate of the University of Western Ontario who has gone on to become one of Hollywood's most trusted makeup artists, replied.

Kayleen has been doing her older sister's makeup since they were youngsters living in St. Thomas, Ont.
