Allison Janney Wins Golden Globe for Her 'Mother... of a Character' in 'I, Tonya'

And the Golden Globe Award goes to … Allison Janney!

The actress took home the statue for best supporting actress in a motion picture at Sunday night’s award show for her role in I, Tonya.

Janney portrayed Tonya Harding’s mom, LaVona Fay Golden, in a dramatized version of the true story of figure skater Tonya Harding.

Janney thanked screenwriter Steven Rodgers in her acceptance speech for creating a “very distinctive, unique, mother…. of a character.”

“What he did is tell a story about class, tell a story about the disenfranchised about a woman who was not embraced for her individuality, tell a story about truth and the perception of truth in the media and the truths we all tell ourselves when we wake up in bed in the morning.”

She also gave a shoutout to flu-ridden star Margot Robbie, who played Harding.

“Margot, my goodness, she’s a quadruple threat,” Janney said.
