And Lily Allen apparently got the memo about wearing revealing outfits.
The 29-year-old dared to bare in a skintight silver jumpsuit which was unzipped to just above her navel, at one point flashing more than she perhaps bargained for while performing at Nassau Coliseum in Long Island, New York on Friday.
Lily's sexy space-age outfit showed off her slender figure and plunging cleavage as she took to the stage.
She had her usually dark locks dyed pink with blunt bangs, dark eye makeup accented with silver glitter eyeliner and a slick of pink lipstick.
While it's unclear if the British singer twerked, she did strut, sway her hips and move her backside to the beat.
This was Lily's first night on Miley's tour and she couldn't be more excited to be there.
'I saw it at the O2 in London [in May], and I'm not exaggerating when I say it's one of the best shows that I've seen in years,' she told Billboard.'It's kind of incredible to watch -- she's a real force.'
The Smile singer had nothing but great things to say about the 21-year-old pop princess.
'She's incredible, and she has such a presence,' she said of Cyrus. 'Her personality is what shines through. I'm not close to Miley, I don't know her very well, but I feel proud of her.'
Another thing Lily appreciates is how the Wrecking Ball singer has transformed her image in the last couple of years.
'It must have been very tough for her to make that transition from the Disney star of Hannah Montana into herself, essentially,' said Allen.
'People don't really like change in this day and age, and not only has she succeeded in changing her complete persona, but she's done it in an in-your-face way, which I love. I'm all for that kind of stuff.'
Lily opens for Miley until August 10th and will then launch her own headlining stage show.
Starting on Sept. 9th in Miami, Allen's Sheezus tour winds through North America before finishing up in Los Angeles on October 10th.
