The expectant mother's family certainly showered her with lots of love, and took some time to pose for a sweet group shot. In the photo, taken by photographer Kristin Burns, Simpson Ross is joined by her 5-year-old daughter, Jagger Snow Ross, her mother, Tina Simpson, and her older sister, Jessica Simpson, and Jessica's two daughters, Birdie Mae Johnson, 1, and Maxwell Drew Johnson, 8.

Simpson Ross shared the photo on Instagram and added the following caption: "I’m so grateful to be with my family as we get ready for my baby boy! Not long now!"

The Simpson sisters also took another photo together and Simpson, 40, appeared to have coordinated her outfit — a brown floral frock and matching hat — with Simpson Ross. Simpson shared a photo on her own Instagram account and called her younger sister her "soulmate, best friend, role model, baby sis."

"This lady right here is someone we should all aspire to be...determined, hilarious, artistic, loving, soulful, wise, loyal and a champion of motherhood!!! I keep telling her that I looked like this 2 months pregnant 😂 When she needs a good laugh I send her pics of my 3rd pregnancy journey! I love you and I can't wait to be an auntie of 3!" she wrote.

Makeup artist Tonya Brewer called Simpson Ross the "cutest mama ever" and Paris Hilton sent love as well, writing, "Such a beautiful family!!"
