Ewan made a moving speech when he accepted the prize, giving a shout-out to his partner, Mary Elizabeth Winstead, who sat in the audience and adoringly cheered him on.
"Mary, I love you so much, I love you so much," he said as he held back a sob, also adding, "We'll take this home and show it to new little boy, Laurie," as he gestured to the award next to him.
The two made their first red carpet appearance since the birth of Laurie in June, and the couple stunned in all-black ensembles.
Ewan also shares four daughters with his first wife, Eve Mavrakis, and gave a special nod to them as well.

He spoke about them at length when interacting with the press, saying, "My kids were texting me in this group chat…they were very present in my mind.
"I have four daughters…and the importance of women and women’s rights…it's so great to be in a room where people are talking about that, so that was moving and important."
When a reporter asked him about whether this was what date nights with Mary had become, he hilariously responded with, "Every night."
Ewan and Mary managed to keep news of her pregnancy a complete secret and the 36-year-old actress was not photographed with a baby bump.
