Dean Sheremet is ready to make an honest woman out of Sarah Silver!

A source tells UsMagazine.com exclusively that Sheremet, 29, proposed to his live-in love Friday morning in their NYC apartment.

"They were having a nice morning together and the moment felt right, so he proposed," a source tells Us.

The Nobu 57 chef, who graduated first in his class from Manhattan's French Culinary Institute in March, "gave her a beautiful antique ring" from the 1950s, set in white gold and weighing in at 3 carats.

"She is an amazing, talented woman," Sheremet gushed to Us in July of his photographer girlfriend. "We have a lot in common and we are both very happy."

Since accepting his proposal, Silver "is elated," says a source. "They're planning on a summer wedding in NYC."

This won't be the first marriage for Sheremet; the former backup dancer divorced country singer LeAnn Rimes in June, more than a year after Us Weekly broke the news of her affair with actor Eddie Cibrian (who was married to model Brandi Glanville at the time).
