Then you're going to LIVE for this video!!!
She's gone undercover -- and she OWNS it!
Ch-ch-check out the video for Birthday here (above)!
Kris Jenner is on the prowl!
The flirtatious momanager, bragged about her close-encoucter with Extra host, by Tweeting this (above) pic, and writing:
"Prom date at XFactor with @mariolopezextra"
We're not sure if this pic was intended to make her husband, Bruce Jenner, jealous or embarrass Khloe…
Either way, the fact that Mario was willing to pose for this picture proves how sweet and charitable he is!
