Fans took to the comment section to point out that Nicole may be hinting at a pregnancy.
"Stunning view! Not going to lie, though, I got excited and thought maybe you were holding a baby bump!!" one wrote, "And I mean no disrespect, it's just the position in which you're holding you hands/ arms."
According to reports earlier this month, a source told top-selling American publication Star that Nicole, who is married to Keith Urban, is currently expecting her third child with the singer.
"Nicole’s confided to friends she’s a few weeks pregnant," the insider allegedly told the publication.
According to Star, "after just one round of IVF" the couple got pregnant.
"Getting pregnant at Nicole’s age without any help wouldn’t exactly be a cinch but fortunately she didn’t have to go through months and months of IVF to make it happen. It’s truly a miracle," they claimed.
Nicole Kidman and Keith Urban got married in June 2006 and share two children together Sunday Rose, 11 and Faith Margaret, 8. Nicole also shares two adopted children with Tom Cruise, Isabella, 26 and Connor, 21.
