Britney, who's had hits with Oops!... I Did It Again and Baby One More Time, believes her Sin City success makes it the right time for a new challenge, an insider tells the National Enquirer.
This is pure imagination and fan fantasy. The source is not revealed, they say she'll do something big during the half time show but never claim she will headline, they assume Miley will join her because she shares manager with her, they assume because of the commercial it means she will headline.
I mean it could happen but this is nothing but just what happens when someone is bored and decides to speculate
She gave gLee their highest-syndicated ratings, the VMAs got their highest ratings ever when she won the Vanguard Award, HIMYM was saved just by her appearance, etc. I'd guess she'd break ratings records if it did happen
