Robert Pattinson and Kristen Stewart were the subjects of Donald Trump's tweets four years ago. Those times were never erased from the "Twilight" star's memory. When she hosted "Saturday Night Live," she opened the show referring to those tweets on October and November 2012. Pattinson's reaction, when asked by a reporter, was hilarious.

Many people were surprised when business magnate Trump tweeted about Robsten's breakup. The tweets that came one after the other only referred to the ex-lovers' relationship and separation as per Gawker.

His first tweet said, "Robert Pattinson should not take back Kristen Stewart. She cheated on him like a dog & will do it again--just watch. He can do much better!" Then followed by another one where he insisted that the "Café Society" actress will cheat on FKA Twigs' fiancé.

The third one was an open invitation for the actor to watch the Miss Universe beauty pageant. The following tweet said that their relationship will be forever broken and can never be restored. The succeeding tweets were all the same telling the "Lost City of Z" actor not to reunite with Stewart.

Few months later, the future 45th President of America greeted Kristen Stewart on her birthday. Many of those who followed the tweets of one of the richest businessmen in the world were surprised. The actors' fans did not believe that Trump was really wishing Elena Gilbert a happy birthday.

Meanwhile, the two actors separately reacted on the tweets at present. According to Gossip Cop, the 30-year-old actor said in a German website, "I hope he has more interesting things to think about now." The "Clouds of Sils Maria" star was asked by Stephen Colbert about her reaction and she just shrugged her shoulders after saying, "That's cool, you know, whatever." Initially, the 26-year-old bisexual said before that perhaps Trump was "in love" with her ex-boyfriend.

It can be recalled that the famous "Twilight" stars fell in love while working on the television series. However, it was marred when Kristen Stewart cheated on Robert Pattinson with director Rupert Sanders. They separated, reunited but eventually went their separate ways.
