She was lucky since there was no YT or twitter back then. This is why I stopped following her like millions of other fans, she doesn't take challenges with her career at all. I don't dislike her though cuz I loved her with all my heart once.
The back up singer sings LEAD in the chorus [or more] in all of these songs...
-If You Had My Love
-I'm Feelin So Good
-Let's Get Loud
-Love Don't Cost a Thing
-Ain't It Funny [Original]
-I'm Real [Original]
-I'm Gonna Be Alright
-Jenny from the Block
-I'm Glad
-Get Right

At least her biggest hit On The Floor is sung by herself (right? )
