*When Christina Aguilera suddenly postponed her U.S. tour this week, her supporting act Leona Lewis was suddenly left all dressed up with nowhere in the states to perform.

Enter Toni Braxton, who is reportedly looking to book the British pop star for her upcoming tour.

“I’ve been talking about touring with Leona in the autumn, Braxton told WENN. “This might happen.”

Braxton will be promoting her new album “Pulse,” while Lewis would continue supporting her Nov. 2009 release “Echo.”
