...And that's probably the understatement of the year!

It was another day, another outrageous outfit for Lady Gaga as she stepped out in Paris rocking a turban headpiece, harem pants, black Slayer t-shirt and a gold beaded chain as the proverbial cherry on top. It must be Halloween but what kind of costume is that?!

The 28-year-old Mother Monster was in the French capital as part of her current ArtRave tour to promote her latest album ARTPOP, a six-month long affair that practically spans the globe.

Besides her latest offering, Gaga has hooked up with the legendary Tony Bennett for H&M's latest campaign to which she could hardly contain her excitement via social media.

"First look at @itstonybennett and me in the @hm Holiday campaign! #HMTonyGaga #HMHoliday," she posted to her Twitter account a couple days ago.

They make a cute pair!
