One is the loneliest number for John Krasinski. The newly beefed-up actor had an uncomfortable time at the 73rd annual Golden Globes on January 10, despite getting the best seat in the house.

Krasinski, 36, went to the awards show alone, because his wife, Emily Blunt, was on location shooting a movie.

"It turns out when you go stag, they put you at a great table," the 13 Hours: The Secret Soldiers of Benghazi actor told Ellen DeGeneres on Friday, January 15. "I was at Leonardo DiCaprio's table. And that sounds really cool except I didn't get a chance to meet him, and I didn't want to be like, 'Hey man, I'm the guy who doesn't have anybody!'"

The seating arrangement turned out to be problematic when DiCaprio, 41, and the rest of his table started winning major awards for their work on The Revenant.

"Then they won everything, so I'm in the middle of hugs," Krasinski quipped of his awkward situation. "People are like, 'This is the best year ever!' And I'm like, 'Wasn't it?!' When they went up and gave their speech, I felt pretty stupid."

The Office alum even had a funny exchange with director Alejandro Gonzalez Iñárritu, who picked up the Best Director and Best Motion Picture — Drama awards for the night.

"Definitely there was that moment  speaking of Alejandro, he said 'hi' to everyone and 'thank you' because they all worked on the movie," Krasinski explained. "And then [he] turned to me and there was that moment of, 'Why are you here?'"

This week Krasinski helped announce the Oscar nominees, which included DiCaprio and The Revenant.
