As their four-year relationship neared its end, the two showed no signs of tension during the Vanity Fair Oscars party in West Hollywood on Feb. 27.
"Jessica was sitting on Justin's lap in a corner in the lounge. She seemed really comfortable and was leaning on him, resting all her weight," an eyewitness told UsMagazine.com, noting that Timberlake, 30, kept "his hand on her leg."
Though Biel, 29, didn't attend the Oscars -- Timberlake brought his mom, Lynn Harless, instead -- the two remained inseparable throughout the evening.
But under the surface, Timberlake and Biel's relationship was about to reach its breaking point.
"The two remain friends and continue to hold the highest level of love and respect for each other," their reps told Us in a joint statement Thursday.
