Biel and Timberlake party together
Jessica Biel and Justin Timberlake have celebrated their engagement with a cocktail party, according to US reports.
The couple, who apparently got engaged in December, were the special guests at a star-studded party hosted by Jessica's stylist Estee Stanley at her LA home, reported People.
"Justin and Jessica arrived at the party looking very excited. Jessica was stunning in a long dress with her hair down," a source told the magazine.
They were joined by a host of their celebrity friends including Timbaland, Ellen DeGeneres, Amy Adams and Justin's former *NSync bandmates Lance Bass and JC Chasez, as well as Jessica's parents.
"Justin and Jessica danced and looked very happy," the insider added.
Following live music and a DJ set, there were speeches including one from producer Timbaland.
"Justin seemed really touched by Timbaland's remarks. You could tell that they have a very special friendship," the source said.
The couple have had an on-off relationship since they began dating in January 2007. They split up in March 2011, before reuniting in the autumn and have not spoken publicly about their engagement or upcoming wedding.
