Jessica seems to be very close with Justin&#39;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&#39;s to come with the wedding,&quot; a source said. Timberlake, who proposed to Biel five years after he first started dating her in January 2007 - wore a black suit, while his 30-year-old fiancee wore a leopard-print halter dress teamed with hot pink shoes and a belt. &quot;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,&quot; the source added.u00a0
