Luke . . . I am your grandchild.

A baby-mama drama is unfolding in Mark Hamill’s family as a former porn actress prepares to give birth to Luke Skywalker’s first grandchild.

Maegan Chen, 30, is suing in a California court to establish paternity and collect child support for a daughter due on Halloween.

But the busty brunette claims the movie star and his family pressured her for months to have an abortion.

“Mark Hamill told me that I shouldn’t bring a child into the world that nobody wants,” Chen told The Post.

She said she met the actor when she stayed with the family in London this spring while the next “Star Wars” installment was being filmed. He told her his son, Nathan, 37, “is not ready to be a father,” she said.

Mark’s wife, Marilou, set up an appointment with a specialist in London to consult on an abortion, Chen claimed. “Nobody ever asked me what I wanted,” Chen told The Post. “I felt really pressured from them to get rid of the baby.”

Chen said she met Nathan Hamill, a toy maker and artist, through Tinder.

Their first date was at a bar in LA on New Year’s Eve last year. Three months after they started dating, Chen, who lives in Las Vegas and works as a model, discovered she was pregnant.

When she told Nathan the news, he immediately urged her to get an abortion, she said. Chen said she complied by taking two pills meant to end the pregnancy. But when the pills didn’t work, Nathan stepped up the pressure.

“If you keep it, we won’t hang out anymore,” said Nathan, according to a text message Chen shared with The Post.

She suspects Mark and Nathan Hamill fear she is gold-digging for the family’s Jabba the Hutt-sized assets. “No money from a trust fund and no money from my parents,” an alleged text from Nathan read. “And you could be paying me child support if I have custody.”

“Just told my dad,” read another purported text from Nathan. “My mom is really upset now. Today’s been a nightmare. I don’t know how I’m gonna last in this house with my family until July.”

Chen said she agreed to a two-week visit with the Hamills in London, where Marilou soon set up a medical appointment for her.

“I thought I was going to get an ultrasound of the baby, not a referral for an abortion,” she recalled. When Chen refused and returned to the US in May, the Hamill empire struck back. In an email from an account linked to Mark Hamill, seen by The Post, Marilou admonished Chen.

“Meagan, you blew it,” Marilou allegedly wrote on June 21.

“I don’t want you to think this is a money making endeavour because you will be extremely disappointed,” wrote the mom, 61, who is the chief financial officer of Hamill’s production company.

Chen broke up with Nathan soon after her visit to London. A spokesman for the Hamills said, “This matter is of a sensitive nature, as well as confidential, and as such, the Hamill family is unable to provide a comment at this time.”
