Elvis Presley's granddaughter Riley Keough celebrated her bachelorette party over the weekend (15-16Nov14) with actress pal Kristen Stewart.

The Twilight star, who met the 25 year old while filming The Runaways in 2010, and four others gathered at the Madonna Inn in San Luis Obispo, California for the festivities.

Keough became engaged to stuntman Ben Smith-Petersen in August (14).

This will be the first marriage for the model-turned-actress.
