Lucy Hale and her Pretty Little Liars co-stars have caused a stir with their "rude" on-set golf cart.

The 25-year-old appears on the teen drama show alongside Ashley Benson, Shay Mitchell, Troian Bellisario and Sasha Pieterse.

During an appearance on Conan O'Brien's show, which is filmed in the same building as Pretty Little Liars, Lucy discussed the cast's pink golf cart. While the girls love it, it's managed to cause quite a stir.

"It's become popular, more than the cast, the pink golf cart!" she laughed to Conan.

"It's decked out with snakeskin seats, fluorescent pink...

"On our show we say b***hes a lot and our slogan is b***hes. So we put it on the back of the golf cart! We got a complaint to human resources at Warner Brothers that we have to censor it. We left it, but now it's censored."

The brunette looked amazing on the show, wearing a short black dress with a deep V-neck and cut-outs at the sides. Conan complimented her outfit and proceeded to query whether they had ever met before.

Lucy recalled a time she'd spotted him in the building and he'd returned her wave.

"Was I pervy about it or cool?" the host quickly panicked.

However, Lucy reassured him he'd been "subtle and sweet".

It seems the star had a great time during her first appearance on Conan.

"Hey @ConanOBrien Thanks for having me on the show last night !! (sic)," she tweeted afterwards.
