Katherine Heigl made a dazzling return to the Emmy Awards on Monday night, gracing the red carpet in a vibrant red gown. The "Grey's Anatomy" star, now appearing in Netflix's "Firefly Lane," expressed her excitement about dressing up, emphasizing that she usually "lives in sweatpants" on her Utah farm.

Before the award show, Heigl shared her joy with "Extra," mentioning that it was the first time she dressed up like this in years. She expressed enthusiasm about reuniting with old friends from "Grey's Anatomy," a show she departed in 2010.

The Emmy Awards featured a notable reunion as well, with the cast of "Cheers," including Kelsey Grammer, Ted Danson, Rhea Perlman, George Wendt, and John Ratzenberger, coming together on stage. Grammer, speaking to Fox News Digital on the red carpet, highlighted the positive feeling of saluting the show's legacy and introducing new talent.

Another reunion took place with Martin Lawrence and his "Martin" co-stars – Tisha Campbell, Carl Anthony Payne II, and Tichina Arnold. Presenting an award, they playfully acknowledged that "Martin" never won an Emmy, expressing excitement to be on the Emmy stage.

"The Sopranos" stars Lorraine Bracco and Michael Imperioli paid tribute to the iconic mob drama during the awards. Standing in what appeared to be Bracco's on-screen office, they introduced the best supporting actress award, commemorating the show's 25th anniversary and remembering their late co-star James Gandolfini.

Overall, the Emmy Awards showcased heartwarming reunions and celebrated the rich history of these acclaimed TV shows.
