Geary, who has been dating singer Robin Thicke since the spring of 2014, announced that she and her boyfriend, 40, were expecting back in August.

In her baby bump debut this month, Geary wrote "already so in love with you" as she caressed her belly. The stunning star has clearly been staying in shape during her pregnancy, as she looks incredibly fit in the mirror selfie.

Geary's initial pregnancy announcement came in the form of a sonogram, which was dated August 14, 2017.

"Robin and I are very exited to share with you all that we're having a baby!" the post read. "The due date is March 1st, Alan's birthday!"

Alan, of course, is Robin's late father, who died last December after collapsing suddenly while playing hockey. The former "Growing Pains" actor's cause of death was later attributed to his aorta artery tearing and then rupturing.

Robin already shared a son, Julian, 7, with his ex-wife Paula Patton. The former couple, who split in February of 2014 after 10 years of marriage, were engaged in a bitter custody battle over their son, but their dispute has since been resolved.
