As you know that  Justin Timberlake and Jessica Biel are going to put a ring on it soon so actress’ stylist, Estee Stanley, hosted an engagement party for them at her El Lay home last night!

Sources are saying that the cocktail party hosted over 100 guests, including Ellen DeGeneres, Amy Adams, Lance Bass, JC Chasez andTimbaland, and the couple “danced and looked very happy” while a DJ played classics like Madonna‘s “Holiday,” Michael Jackson‘s “Good Times,” Whitney Houston‘s “I Wanna Dance with Somebody!”

The insider continues:

“Justin and Jessica arrived at the party looking very excited. Jessica was stunning in a long dress with her hair down. Estee created a very warm, welcoming and festive party for the couple.”

And at the end of the evening Justin apparently even gave a speech by which JT seemed “touched!”

The source explains:

“You could tell that they have a very special friendship.”

It sounds like they had a really good night.

We would have loved to have been there!

But we know the wedding is going to be so much better tho.
