AceShowbiz - Ashley Graham is about to become a first-time mother really soon! The plus-size model has given some updates on her pregnancy, including the sex of her unborn baby as well as her due date, during her appearance on "The Ellen DeGeneres Show".

In the Thursday, November 7 episode of the talk show, Ashley and host Ellen DeGeneres played a round of rapid-fire questions when she made the revelation. "Are you having a boy or a girl?" the comedienne asked, to which the former "America's Next Top Model" judge casually replied, "A boy." She then got all excited and started to shout, "Yeay! I'm having a boy! I'm going to be a mommy to a boy!"

Prior to the baby gender reveal, Ashley offered a few hints about her due date as saying, "This is my last trip I flew just for you." This prompted Ellen to press Ashley to reveal the exact due date, leading the latter to say, "January sometime." However, she noted that her bundle of joy could arrive earlier or later than expected.

Ashley announced that she's expecting her first child with husband Justin Ervin last August, when they were celebrating their ninth wedding anniversary. Unlike most expectant mothers who have a hard time dealing with pregnancy, the Sports Illustrated Swimsuit model said during her appearance on "Ellen" that she's doing great. However, she's so busy that she doesn't have time for naps, so instead she works out.

She told the morning talk show host, "I literally flew in and I'm like, 'Oh my God I'm exhausted. I just need to take a little nap.' But I can because here I am with you. So I just took the three pound weights and I just started doing weights backstage."
