"Tom is thrilled to have new romance since Katie and Jaime [Foxx]'s romance looks to be serious," an insider reveals, "He is no fool and it still kinda irks him that Katie has moved on from their marriage. Tom has not had anyone serious or special in his life since Katie, so he is happy that he finally has something exciting and new. It feels good for him to have someone for himself that takes his mind of his ex Katie and what she is up to."

"He was introduced to [his new girlfriend] by a mutual friend on-set of one of his films," the insider says of his new relationship, "Tom has been dating the new woman for a while and they are working hard to keep the relationship secret until the time is right."

The insider tells HollywoodLife.com, "Things are still fresh and new between them. The secrecy of their romance is making everything fun, sexy and thrilling.
