, skipped the after-parties and opted for dinner with his two favorite ladies – his mom and his girlfriend Jessica Biel
Timberlake and Biel sat side-by-side during the two-hour dinner with a group of friends at Tableau restaurant in the Wynn Las Vegas's Spa Tower. According to a fellow diner, the pair shared kisses and "were so lovey-dovey. They were always touching and being very sweet with one another and in front of Justin's mom."
At the end of dinner, the two, who were expected at parties all around town, called it a night. According to a source, Timberlake wasn't feeling well last night despite his high-energy performances.
On Monday it was reported that the singer was ordered by a doctor to rest his voice after suffering "vocal strain" inflicted during his VMA performance and months of rigorous touring. Two shows this week have been postponed as a result.
