The 48-year-old actor has taken to the streets of New York to take part in the public demonstration against the new American President alongside a number of disgruntled people following the US presidential election on Wednesday, which saw the Republican take victory over the Democratic candidate Hillary Clinton.
The star has shared a clip of him surrounded by hoards of protesters outside Trump Tower in New York on his Instagram account.
He captioned the post: "Love Trumps Hate love fest NYC Thousands in the Street.(sic)."
However, Mark isn't the only one to be in support of the protests as music legends Madonna and Cher have also revealed they are backing campaigns against Donald.
The Like a Virgin hitmaker took to social media to share a video of mass protests taking place to her Instagram account, which sees "rebels unite".
Whilst Cher has revealed she was disturbed by "loud" protesters whilst in her New York hotel but when she realised what the commotion was about she swiftly went outside to hug "many" of those involved and praise them for fighting against the 70-year-old businessman.
She said: "Walked out hotel & in2,NEW YORKERS!! THEY WERE LOUD & PROUD‼ THAT AMERICANS HAVE RIGHT 2YELL HOW THEY FEEL‼ Hugged many.. THEY HAVE SPIRIT (sic)."

Meanwhile the If I Could Turn Back Time hitmaker believes the world will "never" be the same again following Donald's success, and has slammed the former Apprentice mogul as a "petty, vengeful coward" and a "toilet".
Speaking before the result was announced, she posted a series of tweets asking people of colour to vote for Hillary, saying how proud her 90 year old mother was of Hillary, and trying to make sure America did not make the same mistake as Britain with Brexit.
