Brad is also set to marry his partner, Angelina Jolie - who he started dating shortly after splitting from Jennifer - in the coming weeks, and she also wished him well.
The source added: "Brad and Angelina are due to marry in the next few weeks and she wished him all the best for his wedding, too."
Although Jennifer, 43, and Brad don't speak too often, it is thought his mother, Jane, may still get an invite to her wedding, as they remained friends after the separation.
The source said: "Brad and Jen don't get in touch that often as they've both moved on with their lives.
"Jen does still chat to his mum, Jane, so there are rumours in Hollywood that she will make an appearance at the wedding.
"But the guest list hasn't even been started yet, so it's too early to say for sure."
