Ellen DeGeneres is known for her hilarous sketches.

But surprising Jennifer Lopez backstage in a replica of THAT famous green dress, has got to be one of her funniest yet.

In a segment for The Ellen DeGeneres Show, the talkshow host arrives at the popstar's dressing room ahead of one of her Las Vegas residency perfromances, and announces she's there as her backup.

"I'm here to be your understudy!" the time Emmy winner says, pointing to the plunging green dress. "Are you wearing this tonight?"

However the On The Floor singer doesn't look too impressed with Ellen's efforts.

"We don't really do understudies," the 48-year-old says, with a confused face. "It would be hard for somebody else to come in and make believe that they were Jennifer Lopez."

The five minute sketch continues on a hilarous rollercoaster of Ellen trying to convince the superstar she needs her.

She even sings scales in a bid to impress J.Lo ahead of her All I Have performance.

J.Lo wore the infamous plunging green design to the Grammys in 2000 and it's become one of the most iconic images from her career.

Sadly, it doesn't look like Ellen will be appearing on stage in place of Jennifer anytime soon.

But we can totally imagine.
