EMILY Atack danced on the bar on wild night out with Ruby Wax and Mel B.
The Inbetweeners star, 32, and the comedian, 69, left Mel B stunned when they started dancing to her Spice Girls hit Who do You Think you Are.
The trio, who have been travelling across the US for BBC Two’s Trailblazers, let their hair down as they partied in Aspen, Utah.
Emily showed off her trim figure in a tight beige top and cream khaki pants, as she threw some shapes with Ruby who looked cool in a colourful top.
Both women wore cowboy hats and sunglasses as they performed in front of local pub goers.
Ruby said on Instagram: “So we’ve had a few drinks… she’s [Emily] got off with somebody, Mel doesn’t like it. “
“We’ve been drinking whiskey and having whiskey juice…”
Mel B, 46, who is sober, documented their shenanigans on Instagram.
She joked that her co-stars were “embarrassing her on a school night” as she filmed them dancing to her Spice Girls classic track Who do you think you are.
Meanwhile Emily has been keeping fans up-to-date with her trip.

In one shot Emily could be seen sipping on cocktails and enjoying bottles of beers – as well as enjoying cowboy-shaped chocolate desserts.
Elsewhere, the star glammed up for filming – putting on a full face of make-up including false lashes and a dark nude lipstick.
She also has been keeping fans in the know on her stories – where she has been seen kicking back with Mel B and Ruby.
The pals were seen posing with statues of Elvis before heading to a series of cabins to stay in the countryside for the evening.
Emily showed off the huge fireplace and the stunning views of the rolling hills – as well as the cosy sofas for her to kick back in.
