Kristen Stewart got dressed up for the Metropolitan Gala event with one of Robert Pattinson's exes - Riley Keough! Don't believe the news? Here is the photographic evidence too. Check out the pictures below posted by one Instagram user Stacy Ho (Stizzyho), who is also their hairstylist.

Riley briefly dated Pattinson and then broke up. Riley and Kristen have been BFF's on and off for quite some time and even worked together in movie "On The Road."

Kristen opted to go for a metallic look at the gala event. She kept her hair colour as it is - orange. The 24-year-old "Twilight" star stunned everybody with the choice of her dress as she attended the opening of the "Charles James: Beyond Fashion," exhibit at the Metropolitan Museum of Art for the 2014 Costume Institute Benefit in NYC on May 5.

Kristen opted to wear an amalgamation of silver black and gold for the attire, which had sequins, tulle, and feathers too! Kristen opted to keep her eyes smoky and her makeup equally stunning. The dress accentuated her slim waist and her long lanky legs through a see through skirt. Kristen tucked her hair at the back but let the entire orange hair fall over her face in waves.

Kristen has recently been the face of Chanel's Métiers D'Art Paris-Dallas collection and even appeared in the adverts of number of fragrances. Her stylist Tara Swennen made sure that Kristen stood out of the crowd and mesmerized everyone with her punk choice of fashion.

Robert Pattinson's ex-girlfriend completed the look with Chanel Fine jewels and shiny black Louboutin pumps. However, the comments on various gossip Web sites have not been very flattering. Many of Kristen's fans are of the opinion that she could have chosen something more elegant and classy for the event.

"This girl does not have a personality to Rock a dress like this she looks like a dead bird with feathers," writes mekaela at the comments section of Hollywoodlife.com

"Why does she agree to wear this crap. All the other ladies have on gorgeous gowns that make sense. This looks like something in Star Wars," writes a user by the name looks like star wars on the same Web site.
