Yes she would have actually, cause Frank spotted her when Beyonce was practicing for the Deja Vu performance at Fashion Rocks! and it was love at first sight, she is a trained dancer and her hard worked has payed off.
I would think doing a 1 week promo tour with Ciara to make some cash is a little different then rigorous hours of tour rehearsal all around the world with Beyonce, when you just recently had a baby.
