WATCH: Katy ranks her exes' bedroom skills

The K.Pez train is taking some crazy detours – and the livestream she’s currently doing to promote her new album Witness is the gift that keeps on giving.

After crying in a therapy session and venting about her Taylor Swift feud, Katy decided to spill all about her ex-boyfriends' bedroom skills. Watch the TMI video above!

And although it’s kind of crazy, we’re so here for it.

The dirty talk all kicked off when Late Late Show host James Corden rocked up to Katy’s temporary house where the filming is taking place, waking her up.

The pair played a truth or dare style game, daring each other to answer questions in order to avoid eating disgusting food items like bird saliva.

Of course, cheeky James pushed the envelope and asked Katy to rank her ex-boyfriends Diplo, Orlando Bloom and John Mayer in order of worst to best in bed!

“No! No! No!” Katy yelled before confessing: “They’re all awesome…I’d have sex with all of them when I finally get out of here.”

James was forced to guess the order, and went with Diplo as worst (to which Katy reluctantly nodded), then John Mayer, then “Bloom”.

Katy shook her head, indicating that the final two should be swapped, with John, er, coming out on top!
