  We show that two Hamiltonian isotopic Lagrangians in
(CP^2,\omega_\textup{FS}) induce two Lagrangian submanifolds in the one-point
blow-up (\widetilde{CP}^2,\widetilde{\omega}_\rho) that are not Hamiltonian
isotopic. Furthermore, we show that for any integer k>1 there are k Hamiltonian
isotopic Lagrangians in (CP^2,\omega_\textup{FS}) that induce k Lagrangian
submanifolds in the one-point blow-up such that no two of them are Hamiltonian
isotopic.
