When the star received the Choice Comedian honor, the comedian shared several profound life lessons. "It feels good to be chosen, but there was a time in my life where I was not chosen—I was the opposite of chosen because I was different. And I think I want to make sure that everyone knows that what makes you different right now makes you stand out later in life,​" she said. "You should be proud of being different. You should be proud of who you are." A proud Portia de Rossi then blew a kiss to her wife, who mentioned that the couple had tied the knot seven years ago.

3. Presenters Rita Ora and Scott Eastwood heat up the stage.
