Who says a kiss is just a kiss?
It all started when Spears complimented the Material Girl on her latest collection of music, MDNA.
"Love the new album," she tweeted. "Every single song is incredible."
To which Madonna replied, "Please come on stage and kiss me again. I miss you!!"
Spears then teased, "Why of course!"
Something tells us these two just moved to the top of MTV's invite list for this year's show.
