Rachel McAdams made her Met Gala debut on Monday night at the Metropolitan Museum of Art in NYC. The actress wore a pale pink Ralph Lauren Collection silk evening dress with a chiffon train, looking gorgeous as she strutted down the red carpet at the Anna Wintour Costume Center. Though Rachel displayed major PDA with her new boyfriend, Patrick Sambrook, in Toronto last week, she walked solo on the carpet. This year's gala celebrates American-based designer Charles James. He was best known in the '40s and '50s for glamorous ball gowns that highlighted a woman's curves. Don't forget to check out the all-time best dressed guests from the Met Gala!
