The two actresses will be starring in an E! Entertainment special this week called Vanessa & Ashley: Inner Circle and have allowed a camera crew to accompany them around Los Angeles, as they hit the dance studio, ride around in their cars and gossip about boys.
In a new promotional clip, 24-year-old Vanessa is seen partaking in the dance craze of the moment, 'twerking', and also admitting to Ashley that she would prefer to lock lips with a girl rather than a guy!
During a sit-down together, Ashley grills her pal on her on-screen kiss with actor James Franco in the Spring Breakers film and the pair also discuss a number of other juicy subjects, such as Vanessa's first time trying out a stripper pole.
The voice over explains: "When your best friend is asking the questions, she's going to get a real answer."

However, it isn't just Vanessa that will be opening up, as Ashley is set to reveal her fair share of secrets too while hanging out with her bestie.
The Hollywood starlets have been close ever since they starred in High School Musical together, so this E! special is certain to be packed full of laughs and fun stories.
Vanessa & Ashley: Inner Circle is set to air on E! in the US at 10pm on 8 August. We'll be keeping an eye on the UK listings for an air date over here!
