Justin Timberlake Parties Until Dawn in New York City

Star closed down Club Avenue at 6 a.m., source tells E! News

Justin Timberlake has been burning the midnight oil—right on through till dawn!

A source tells E! News that the "Suit & Tie" singer partied all night Monday in New York City, ditching Catch restaurant in the Meatpacking District at around 4:30 a.m. for Chelsea hotspot Avenue, where he remained until 6 a.m.

Wife Jessica Biel was nowhere to be seen, making it a guys' night for Timberlake.

He was also spotted out Sunday night with three male pals at 1-OAK in Chelsea.

We're told (and we can see) that Timberlake wasn't too thrilled with the paparazzi detail on his trail.

Biel, meanwhile, was up to more domestic pursuits today, posting an adorable photo to Instagram of her pit bull, Tina, lying underneath a pile of folded laundry.

"You know that thing where you eat sushi off a model? This is my version. #TuesdayswithTina #laundryday," she wrote.
