On Instagram, April sported a make-up free face while wearing nothing but white Calvin Klein underwear and a gray bra.

The mother-to-be held her lower tummy as she snapped a quick photo in the couple's bedroom mirror. 

While being in her third-trimester, April captioned her photo: '31 weeks today! HOME STRETCH.'

Just hours before posting her photo, April and Robin were seen arriving to the dry cleaners with a pile of clothes.

Robin carried multiple jackets, while the brunette beauty carried a paper bag and a pink hoodie.

The California-born model dressed for comfort in tight black leggings and a white long sleeve shirt.

April also appeared to be missing her shoes, as she was seen only walking in her white socks.

Robin spent Christmas with April's family on Monday, and the 23-year-old made sure to share some sweet moments on her Instagram.

In a video with the father of her child, April is seen holding up mistletoe while kissing the singer.

She also posted a picture with her older sister caressing her stomach with the caption, 'My lil big sister'.

Although this is April's first child, this will be baby number two for Robin.
