His character finally got married — and now Chris Noth is planning a “Big” day of his own!

The Sex and the City star was at STYLE360’s Caravan and Oral B fashion show today with his long time partner Tara Lynn Wilson — who was sporting a HUGE rock on her ring finger.

When OK! offered Chris — who is reprising his role of Mr. Big in Sex and the City 2, which is shooting in NYC right now — our congratulations he beamed: “Thank you!”

The happy couple, who have one child, Orion, together and have been dating since 2004, sat front row at the show smiling, holding hands and whispering to each other throughout the show.

“It all happened very recently,” said an insider. “This is the first time they’ve appeared in public with her wearing that huge diamond.”
