And she also didn't come along with Miz to a wedding which he has been invited to for months. If they were a couple before, they aren't anymore for sure right now.
IF they broke up it had to be in like the last few weeks considering Miz' hilarious thigh rant was a month ago and they slept in one bed a month ago. However I don't think anythings indicating they broke up to begin with so. The clip too is obv banter and Emis immediate nervous response seems more like a "fuck she almost leaked it" kind of response.
