Meghan Trainor is having a moment.

The 'All About That Bass' singer is blowing up on TikTok, sharing plenty of relatable parenting content — and she has a pregnancy book being released, too. The Grammy Award-winning musician has used social media to not only promote her new music (obvs) but also give fans a glimpse into her life.

In case you weren't across it, Trainor, 29, is married to Daryl Sabara, 30, the actor best known for playing the lead in the iconicSpy Kidsfranchise.

They have a one-year-old son together, and according to a recent interview, want a "farm" of children.

And recently, the couple announced that they are expecting their second child. But as they await the delivery, Trainor has opened up about her first birth experience, saying it was 'traumatic' and left her with PTSD.

Watch the moment when Trainor and Sabara share their pregnancy news. Post continues below.

In an excerpt from her new book,Dear Future Mama– a "TMI [too much information] guide to pregnancy, birth and new motherhood" – Trainor has shared that she was diagnosed with PTSD following her 'traumatic' birth experience.

In the excerpt published in PEOPLE, Trainor wrote, "I couldn't go to sleep at night. I would be in tears and tell Daryl, 'I'm still on that table, dude. I'm trapped there. I can't remind myself I'm in bed and I'm safe at home'," she said.

Trainor explained that for months after the birth she would "cry every night" and go to bed and continue to "feel the pain" of the C-section.

Trainor said "therapy and time" have played a role in her emotional recovery, with her therapist telling her "it's chemical reactions in your brain".

Trainor opened up in her new book about the influencer parenting content she sees online, saying she found a lot of it quite unhelpful in the lead up to giving birth.

"Every day I saw a new YouTube video about 'what I really used in the hospital.' Let me tell you this: I learned absolutely nothing. They were all wrong. I love influencer content, but it's designed to sell you an aesthetic, and childbirth is not aesthetic," she wrote.

"Maybe I'm just jealous, but I'm not the kind of person who is going to pack multiple outfits for a surprise outfit change. But watching all this stuff made me want to be that person."

Trainor and Sabara's relationship started a little something like this:

In 2014, the singer and actor met at a house party, months before Trainor's hit single 'All About That Bass' came out.

She went up to Sabara while he was grabbing a drink.

"I was like, 'Are youSpy Kids?' And he was like, 'Yeah.' And I thought that was so cool," Trainor told People in 2019.

"I called my entire family and was like, 'I partied withSpy Kidslast night.'"

Then, in July 2016, Trainor asked her friend, actor Chloë Grace Moretz, to set her up with a "nice guy". She suggested Sabara.

"I know the nicest guy in the world, Daryl, and you should meet him," the singer told the publication.

Trainor and Sabara went on their first date soon after — going bowling and singing karaoke — with Moretz and her then-boyfriend Brooklyn Beckham.

"I thought, 'I'm gonna karaoke with a Grammy winner, this'll go over well,'" Sabara recalled.

But theSpy Kidsactor's rendition of the Elton John classic 'Your Song' impressed Trainor.

"We had a great night, and I've hung out with him every day since," she said.

After a year and a half of dating, Sabara proposed to the singer the night before her birthday, on December 21. Sharing the news on Instagram, Trainor wrote: "I SAID YESSSS!!!! For my 24th birthday, the love of my life made all of my dreams come true."

"He proposed to me under a tunnel of beautiful Christmas lights and surprised me with my family and friends. I’m still in shock. I’ve never been this happy," she added.

The couple tied the knot the following year on Trainor's 25th birthday, at an intimate ceremony in their backyard with 100 friends and family. They spent their honeymoon in Bora Bora and invited their parents and siblings, calling it a "familymoon".

"That was the best part," Trainor told E! News.

"I loved being with Daryl alone, but the familymoon was all the best memories of my entire life."
