Not sure how I can go about doing this- Hannah Montana bard

Hello!

For my DM's next campaign, she wants us all to be spell casters who graduated from a magic college-type vibe (it's a really cool idea that she's come up with). In my last campaign, I felt I was a bit too gloom and doom, while also not feeling like i was very good at understanding who my character was. She was meant to give off "chosen one" vibes, which I fear came off more as "pick me girl" vibes ahhh. 

In our next campaign, I want to be a little less like that. I was maybe thinking of being like Hannah Montana, in which I am a Bard that everyone thinks is in the College of Eloquence with the intention of becoming a politician (since that is what her parents are). However, at night, she is actually part of the College of Glamour, in which she is basically a pop star. I thought this would be silly and a little less deep compared to my last character. 

My only issue is how I go about trying to get people to think I am in the College of Eloquence instead of Glamour. Moreover, how can I build my character's spells to get people to think she is not part of Glamour?

Not sure if this makes any sense hehe. Thanks! 

Plot Twist:She's double-deceiving, & is actually a Whispers Bard.

Jokes aside, Changeling is the species to go with. Picking up some way to alter your voice would be ideal, RPing the character as being knowledgeable(int) and/or street smart(Wis) in her "normal" persona, then pretending to be less Int, & even more Cha & some Dex for flair when in "pop star" mode.

 Tell the other players the concept; they'll play along.

If I recall, a lot of people knew her secret identity.  But the total amount of people that knew were not telling anyone and helped her keep it.

Write up the sheet as how the character actually is and the actual attributes/skill/spells/etc.  Then maybe create a second one that is more "public" that states what she is suppose to be, but use the 1st sheets actual skills/scores

I would second the idea of letting the party know, and have the dm play the npcs as not knowing. 

Having the party go along with and help protect your identity will just work a lot better than lying to your own party all the time.

As for spells, if your cover identity is Lore bard, you can pick spells from a wide spell list starting at level 6. 

If you can play a changeling bard, woot, that has been on my list of builds i want to play some day.

100 percent this. I played an undead tome warlock once who had a wand that contained the spirit of an archmage that was the source of his powers, so he told everyone he was a "wizard". The party was in on it and played along, even when I would cast my "frosty ray" (eldritch blast with Lance of Lethargy), and called me the smartest wizard they knew
