How Tom Brady Feels About Gisele Bündchen's Surprise Marriage to Joaquim Valente

• Gisele Bündchen and Joaquim Valente got married on December 3.
• Sources have weighed in on how Gisele's ex, Tom Brady, feels about her moving on.
• Tom is doing his best to be "mature" for the sake of his kids.

Gisele Bündchen tied the knot with Joaquim Valente in a "secret ceremony" on December 3, and if you're wondering how Tom Brady is feeling about his ex officially moving on, sources are spilling.

An insider tells the Daily Mail that Tom was told Gisele would be getting re-married ahead of time, saying "It wasn't a secret to him. They still have to talk because of the kids, and though that is often very brief, important milestones, schedules and of course her getting married was something she wasn't going to keep secret."

Apparently, Tom is trying to be "mature" and the source says "He's happy in the way that is simple: he's happy that she is happy. Down the line he might get married again and he would want her to be OK with that, so he has to be OK about it. If he was upset, that would mean he still has feelings for her and that it would be unfair to the kids if he didn't want to see their mom happy and move on. He's had to move on from two different important relationships, and two mothers to his children. He's learned a lot along the way, and he's taking this next stage in stride. He's being very mature about it and not letting it pick at him negatively in any way."

"It's life, and everyone is happy," they add. "It's the holiday season, he's not inviting any drama where there doesn't have to be. They are living their own separate lives and anything that actually matters is the safety and happiness of their children. That is everything for Tom."
