"Oh f*ck" is right.

Ex On the Beach, featuring unassuming singles and their former flames showing up to shock them, is returning for Season 2 on December 20. Hosted by multi-platinum rapper and actor Romeo Miller, the infamous dating series follows reality stars -- from Are You The One?, The Bachelorette, Bad Girls Club, Big Brother, The Challenge, Survivor and Teen Mom (to name a few) -- as they search for new love while being blindsided by their past romances. The sexy/dramatic water entrances are back.

And in the first look below, a familiar MTV face isn't too pleased about what's unfolding in hell paradise.

"Are you okay?" Farrah Abraham angrily asks a mysterious man.
