Hot mama-to-be alert!

On Saturday, Morgan Stewart showed off her growing baby bump for the first time, posing in a black bikini.

“Can we get this emoji a bikini please….,” the expecting E! personality quipped on Instagram.

The 31-year-old, who announced her pregnancy in August, a month after getting engaged, received sweet replies in the comments, including a message from fiancé Jordan McGraw.

“Bumping it up a notch…,” 34-year-old McGraw posted.

Stewart confirmed in March that she and McGraw, the son of TV’s Dr. Phil McGraw and wife Robin, were an item. The couple celebrated their engagement over the Fourth of July weekend.

Last month, Stewart and McGraw confirmed they were expecting a girl.

“She may not be great at math but at least we know she’ll be well dressed,” Stewart shared from the couple’s gender reveal.

Prior to her romance with McGraw, Stewart married fellow “Rich Kids of Beverly Hills” star Brendan Fitzpatrick in 2016. She filed for divorce last fall.
