Meghan Trainor Shared The Emotional Moment She Found Out She's Expecting Baby #2

Last week, Meghan Trainor announced that she's expecting her second child with husband Daryl Sabara. After talking about how much she wants more kids for a while, the excitement of being pregnant again is undeniable for the singer. She recently shared the emotional moment she saw two lines on her pregnancy test on social media.

Trainor hasn't been shy about talking about her desire to have many babies, so finding out she was expecting her second child was a bit of an emotional moment for her. She recently shared a video on TikTok and Instagram that shows the moment she saw there were two lines making a plus sign on the pregnancy test. The video was set to the song, "Turning Page" by Syndney Rose.

Many friends and fans dropped into the comments on both Instagram and TikTok to share their excitement for the singer. Sirius XM Hits One wrote, "beyond happy for you 💞💞💞." Actor Jeremy Renner wrote, "Congratulations 🎊 ❤️."

One fan wrote, "Happy for the both of you, and congrats on baby number 2. Riley is going to be the best and the coolest Big Brother to either a baby brother or baby sister.🤍🤍🤍" Another added, "Thank you for allowing us to share in this special and Beutiful moment, congratulations on spy kid baby #2 Wish you nothing but health and love!"

Trainor, 29, and Sabara, 30, are already parents to son Riley, who's about to turn 2 this month. The singer recently told PEOPLE that she's halfway to her goal. "I'm just so grateful I can get pregnant. And I'm like, 'I'm crushing it. This is amazing. This is my dreams,'" she said. "I'm halfway there - I want four kids."

Trainor is currently about four months pregnant and said this pregnancy is "like a real pregnancy." "The first one was like make-believe. I had no symptoms with Riley to the point where I was like, 'We need to go to the doctor. There's nothing in me,'" she said. "I got my symptoms late in my pregnancy with Riley. I got them right away with this baby."

She explained that she got red perioral dermatitis all over her face, her belly popped earlier this time around and she was very nauseous. "This one was a ride. It was a rocky ride, but luckily it was during the holidays, so I could just chill and lay down," she said.

This time around, she's also experiencing cravings. "I didn't feel extra hungry with Riley. This time I'm like, 'I need a pickle.' Even if I'm having chocolate or sweets, it needs to be followed with a pickle," she said. "It's weird, but it's great. I'll eat a whole meal, and then I'll be like, 'I could keep going.'"

The same day she announced her second pregnancy, she also announced her new book, "Dear Future Mama: A TMI Guide to Pregnancy, Birth, and New Motherhood from Your Bestie," which will be released on April 25 with Harper Horizon. The book details Trainor's own journey to motherhood with lots of TMI information on conception, pregnancy and childbirth.

"I'm an open book, and I love telling everybody everything about my grossness and all my truth," Trainor told PEOPLE. "When someone goes, 'Oh my God, me too,' then it makes me feel like I'm not alone, and I'm like, 'I'm not weird, my body's not different. It's normal.'"
