Oh baby, baby, how was she supposed to know? Britney Spears is hilariously admitting to not knowing who legendary musician Mick Jagger was back in the day, when the two carried on an awkward conversation ahead of the 2001 MTV Video Music Awards. The pop star took to her Instagram to recap their informal meeting, writing beneath photos of the two, "I had no idea who I was talking to." At the time, both Spears and Jagger were on the verge of album releases, with Spears' third-studio album "Britney" and Jagger's fourth solo-album separate from the Rolling Stones, "Goddess in the Doorway." Spears was a performer at the awards show while Jagger was a presenter. MTV host Kurt Loder, taken aback by the pairing, asked Jagger if he was a fan of the young artist.
