Britney Spears’ ex-boyfriend is coming to her defense.
In an exclusive interview with The Post published Friday, the star’s high school beau Donald “Reg” Jones slammed Justin Timberlake for asking her to abort the child they accidentally conceived.
“Any man that is gonna ask a woman to have an abortion? Then he is a piece of s–t in my book,” Jones, 45, said.
Spears, 41, revealed in her new memoir, “The Woman in Me,” that she became pregnant with the *NSYNC singer’s baby during their relationship, which lasted from 1999 to 2002.
She claimed she would have kept the baby if it was solely her choice.
“I loved Justin so much. I always expected us to have a family together one day,” she wrote. “This would just be much earlier than I’d anticipated.”
“Any man that is gonna ask a woman to have an abortion? Then he is a piece of s–t in my book,” he slammed in an interview with The Post Friday.
He and the “Slave” hitmaker dated between 1996 and 1998.
“But Justin definitely wasn’t happy about the pregnancy. He said we weren’t ready to have a baby in our lives, that we were way too young,” the “Toxic” hitmaker claimed.
“I’m sure people will hate me for this, but I agreed not to have the baby,” she continued.
“I don’t know if that was the right decision. … And yet Justin was so sure that he didn’t want to be a father.”

She also revealed the “excruciating” abortion was done at home so absolutely no one would find out.
Spears and Jones dated not long before she got with Timberlake, from 1996 to 1998.
In his interview with The Post, he seemingly regretted that Spears left life with him in Mississippi at all.
“She didn’t want to go do Hollywood. She’d been there dancing, singing long enough,” he claimed.
“And she was just wanting to be normal and live a normal life and go to high school, and stay datin’ me I guess. Whatever.”
“But as far as the Hollywood, that crap? Look at the road it took her down,” Jones continued. “My heart goes out to her.”

Jones is among the thousands of people who have expressed their disappointment in Timberlake after learning about the abortion he allegedly encouraged Spears to have.
The backlash got so bad that the “SexyBack” singer turned off his Instagram comments this week.
The move seemingly backfired, as it encouraged trolls to shamelessly migrate over to his wife, Jessica Biel’s, Instagram page to share their frustration.

A person close to Timberlake revealed this week that he’s “not at all happy” with the revelations in the book.
Amid the memoir fallout, however, Timberlake was supported by his bandmate Lance Bass, who told TMZ on Friday that people should give him grace.
“I feel like the world is so full of hate right now and we need to practice a little forgiveness,” he stated. “Britney did. Let’s take a note from her.”
