Justin Timberlake and Jessica Biel are ready to tie the knot, but not before celebrating with their friends and loved ones first!

On Saturday, stylist Estee Stanley threw a big engagement party for Justin, 31, and Jessica, 30, at her private home. As Biel’s longtime stylist, Stanley spared no expense and invited 100 guest to celebrate the A-list couple’s upcoming nuptials.

Who was there at fancy soiree?

The impressive guest list included big names like Ellen DeGeneres and her partner Portia DeRossi, Amy Adams, and Justin’s ‘N Sync buddies Lance Bass and JC Chasez.

“Jessica and Justin were mingling both separately and together throughout the party,” a partygoer spilled to Us Weekly. “Jessica seems to be very close with Justin’s friends and vice versa. You can see that they have been dating for a long time and really know each others friends and family well. The party was a fun celebration and a preview of what’s to come with the wedding.”

Sporting a black suit and fedora, the Friends with Benefits actor sipped on wine and champagne and noshed on bites by Wolfgang Puck. Meanwhile, his 7th Heaven ladylove was seen in a leopard-print halter dress cinched at the waist with a pink belt for the special occasion.

The couple of five years reportedly left the party at 12:30 a.m. to return to their Hollywood Hills home.
