The Friends star was a guest on the American show and wowed the gathered crowd in an amazing figure hugging Dolce & Gabbana shift dress and grey Gucci heels.
This was the second TV appearance for Jen that day as she previously stopped by Good Morning America looking equally as gorgeous.
On the show, Jen revealed that back in the 90s while still filming Friends she actually dated the show's host Jon Stewart, but unluckily for Jon the date didn’t go that well!
We can't wait for Jen to hit the promotional trail for her new movie The Switch over here.
