• Meghan Trainor is all about that bump!
• The singer is presently expecting her second child with husband Daryl Sabara.
• She posted a video on Instagram flaunting her baby bump.

The singer, who is presently expecting her second child with husband Daryl Sabara, posted a sweet video of herself dancing to her upcoming song “Mother” on Instagram on Friday.

The 29-year-old Trainor could be seen in the video sporting a sparkly two-piece outfit that highlighted her burgeoning baby belly and revealed her midriff.

Riley, her 2-year-old son, also made an appearance on the video. Riley was first seen to the side of the camera’s field of view before latching on to his mother’s leg.

“Riley is ready for #MOTHER 🤰💖 3.10 💖,” Trainor captioned her post, adding the hashtags, “#IAmYourMother” and “#21WeeksPregnant.”

Trainor and Sabara, both 30, announced the wonderful news of their impending second child together earlier this year.

“What a blessing,” Trainor told PEOPLE exclusively in January. “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 added. “I’m halfway there — I want four kids!”
