It's not the first time the Sports Illustrated model has shown off her growing stomach, recently wearing a suggestive swimsuit which proudly flaunted her bump.
The black and white swimsuit featured cheeky cut-outs around her stomach with a scoop neck and plunging backline.

In both posts, the Cravings author is comfortable in her skin, after getting her breast implants removed.
"They've been great to me for many years but I'm just over it. I'd like to be able to zip a dress in my size, lay on my belly with pure comfort," she explained in June when she had the surgery.
Chrissy and husband John Legend, parents to Luna, 4, and Miles, 2, announced that they were expecting their third child earlier this month via John's music video for Wild.
At the end of the clip, Chrissy cradled her bump on the beach while John hugged her from behind.
The couple have not announced a due date, but the child is expected to arrive in March, 2021.
They welcomed their daughter Luna in 2016, and son Miles in 2018.
Before Teigen had even given birth to Miles, she spoke to US Weekly about their plans for a third child.
"I think I do want to have another baby after this and then get hot," she said.
"I just want to go babies, back to back to back, but then I think maybe I want to have my 30s, really live in my 30s and not just be pregnant throughout them."
Legend and Teigen married in Italy in 2013 after first falling in love on the set of his music video for Stereo.
