Fashion designer/Bravo reality TV star Rosie Pope, 33, is having a new addition to her growing family. The "Pregnant in Heels" star is thrilled to announce that she is expecting another child with her husband Daron Pope. The baby will be their fourth child together.

"We couldn't be happier to be having another baby," she said to PEOPLE. "We feel so blessed and the rest of our brood are so excited to have another baby in the house." On Twitter, she added, "Thank you so much everyone for your congratulations on baby #4. We are so excited! Xo."

She didn't reveal her due date, but hinted it could be early next year. "Looks like it will be a busy start to 2014!" so she said. The baby will join big brothers J.R., 4, & Wells, 2, as well as big sister Vivienne, 15 months.

Rosie struggled to get pregnant with her second child. She underwent in vitro fertilization treatments and had one of her fallopian tubes removed in the process. Six months after Wells was born, she got news from her doctor that she was pregnant with her first daughter.

"Pregnant in Heels" documents Rosie's work to help pregnant mothers with their odd baby needs while she's running her maternity clothing boutique. The show has wrapped its second season last summer.
