Jennifer Aniston, Justin Timberlake Help Ellen DeGeneres Celebrate 2,000 Episodes

Congrats Ellen DeGeneres – you don't look a day over 1,999!

"The Ellen DeGeneres Show" celebrated its 2000th episode milestone on Thursday with some special surprise guests – Justin Timberlake and Jennifer Aniston.

Jen was the first surprise guest to help Ellen celebrate the honor, with a "Welcome" mat in hand – the same gift she brought to Ellen on her very first show as her very first guest.

Jen then helped bring out the next surprise – Justin, who was Ellen's second-ever guest when she launched the show back in 2003.

The surprise was a rare fete, as Ellen admitted she often finds out about most things ahead of time.

"I thought for sure you knew or you'd find out," Justin said.

"I know. Even when Portia tries to surprise me, it always leaks out, somebody tells me something," Ellen said. "You are two of my favorite people."

Later in the show, "Scandal" star Kerry Washington also joined the celebration, and came toting a bottle of red wine and two "official Olivia Pope wine glasses, because they are ginormous!"

"You are the only person I know who loves red wine more than Olivia Pope," Kerry joked.
