A supporter of Republican President Donald Trump was physically attacked after her sign was grabbed and torn outside the Oscars awards show Sunday in Hollywood.

But the Trump supporter — wearing what looked like a red "Make America Great Again" baseball cap — didn't take the attack lying down, and was soon swinging her fists back at the woman who started swinging first.

Another female, apparently the attacker's friend, also got into the act and even held on to the attacker as a police officer was making his arrest.

But the cop wasn't having it, telling the attacker's friend that she needed "to let go, or I will put you in handcuffs."

The attacker's friend also was seen on video clashing with a male Trump supporter who told her she's "fake and phony" and has "no respect."

In a snippet from the same video — which may have been prior to the arrest — the attacker's friend, with the attacker by her side, apparently had enough of the Trump-supporting man arguing with her.

Thinking quickly on her feet, she flipped him off then turned around and grabbed her rear end.

The incidents reportedly were reactions to a larger protest and boycott of the Oscars.

Here's the video. Only in Hollywood:
