Taylor, 37, shared a picture of him with former hockey player Bryan Bickell.
A follower commented under the post, "Stoked you got away from Gaga. #Hollyweird," which he later liked.
The Oscar winner's fans were quick to jump to her defense."Imagine being bitter and liking shady comments after someone's success," a follower commented. "I had so much love and respect for you until you liked this s**t. Way to trash someone you were once going to marry," someone else wrote.
After realizing what he did, the Chicago Fire star clarified. "Sorry for the 'like.' It was an accident. I’m only proud and happy for Stef,” he said.
