"Thank u to everyone for all the kind birthday wishes!! It's been a fantastic day with my family! #40thbirthday," Pressly captioned a sweet photo from her family beach day, as she flaunted her baby bump in a cute black-and-white bikini.
The blonde beauty announced that she and Hamzi Hijazi were expecting twins in June.
"Twins don't run on either side of our families, so we were completely shocked," Pressly told People at the time. "This wasn't IVF or anything like that. It was just a shock, and I'm like, 'Doctor, that's impossible!'"
"I've always wanted three kids and the older I'm getting, I'm like, 'OK, maybe just one more would be nice,'" she added. "I was getting a little sad, but it was like, 'We'll give you two in one. You don't have to do another pregnancy.'"
