Now together publicly, The Bachelorette star Ashley Hebert and J.P. Rosenbaum, her final rose recipient, seemed in great spirits in NYC last weekend.

The duo went to downtown hotspot Beauty and Essex for dinner on Friday. Ashley was "so sweet and nice and took pictures" with fans, sources say.

Saturday morning, Ashley Hebert and J.P. Rosenbaum had breakfast at Coffee Shop in Union Square, then spent time walking around with friends.

Also on hand? Hebert's once-disapproving sister, Chrystie Corns!

Ashley's elder sibling infamously disapproved of J.P. on The Bachelorette finale, but according to a source, the two are "on very good terms now."

That's good to hear. Latert, Rosenbaum threw an engagement party of sorts so his friends could meet Hebert. About 40 people met at Casa La Femme.

After dinner and dessert, it was time for some belly dancing! "Ashley danced with the belly dancers. She's such a good sport," says the insider.

The best part about their relationship? The source says:

"That they don't have to keep this a secret anymore. They're so happy to be a couple and show everyone how in love they are with one another."

Will Ashley and J.P. last? It looks like it, so far ...
