Gisele Bündchen got emotional talking about her ex-husband, Tom Brady, and their high-profile divorce … and in the same breath, she refused to discuss her new romance.

The supermodel spoke with ‘GMA’ anchor Robin Roberts in a new special that aired this week — and she asked the one question everyone’s been wanting to know … how has she been since ending things with TB12, and what’s her dating life like now?

Gisele was willing to address the former, but not the latter … and while she responded to the Tom question — she actually teared up, having to turn away from the camera for a bit.

She says she’s in the middle of a transition that had to take place — something she notes she never wished for in her marriage with Tom … but which unfortunately became their reality.

Despite the sad ending, Gisele says she wouldn’t change anything … noting she’s grateful for her 2 kids she shares with her ex, calling them the ultimate blessing in her life.

Gisele goes on to say she’s in a new season right now, and is embracing it head-on.

In terms of talking about her new boyfriend, Joaquim Valente … that was apparently off-limits during this interview. Gisele is never heard even saying his name — it’s just Robin noting that Gisele wanted to keep her personal life private … even though it’s clear what’s up.

Joaquim continues to be seen at Gisele’s pad in Florida — in fact, they were seen leaving her crib on Wednesday … and even Tommy was spotted out and about the same day.

Tom’s moved on himself, obviously … he’s been dating Irina Shayk on and off for the past year — and while we know he’s questioned the timeline of Gisele and Joaquim getting together … it also seems like he’s over it and turning the page.

Like Gisele says … a new day is upon us.
