After the news of Arnold Schwarzenegger's affair sent the media into a feeding frenzy and forced the former governor's lovechild and mistress into hiding, Radar Online reports that Schwarzenegger has been taking secret trips to visit the pair and get to know his son, Joseph.

"Arnold wants to spend time with Joseph and play more of an active role in his life," a source told Radar. "In a way, Arnold is relieved that he no longer has to hide the fact that he is Joseph's father."

But 'The Terminator' hasn't been the only one making the secret trips, the source also revealed that 13-year-old Joseph and his mother, Mildred Baena, have been spending time at Schwarzenegger's Brentwood, California home, where they have been continuing to foster a father-son relationship.

"Arnold apologized to Joseph because he had to miss the last few weeks of school, and Joseph said he had no problem missing school and could forgive him for that," the source said. "It was a really tender moment between father and son."
