Tripp is the first child for both McCarron and Webb, a former Miss Alabama, who began dating in 2012 and then married in July 2014 in Orange Beach, Alabama.

The pair announced in December that they were expecting their first child together, months after she opened up about the couple's struggle to conceive in a heartfelt Instagram post.

And since sharing their happy news, Webb has been sure to keep her friends, family and fans updated on her pregnancy progress, sharing images of her baby bump on Instagram at regular intervals.

Just last month, the brunette beauty showed off her swollen belly with another selfie, taken in the same bathroom mirror, this time wearing a more revealing ensemble of a black bra, paired with black sweatpants.

'Feeling him move is the craziest feeling,' she wrote in the Instagram caption for a picture that shows her proudly checking out her belly in the bathroom mirror.

'Love watching AJ snuggle with the bump too,' she added.

Katherine shared the first picture of her baby bump in December, just two weeks after she and AJ announced that they are expecting a son together.

Snapping the selfie in the mirror of her doctor's office, Katherine lifted up her long-sleeved top to reveal an almost-completely flat stomach, showing off just the tiniest hint of a baby bump, while the rest of her physique appeared as lean and toned as ever.

'Bubs trying to make an appearance for the Doc,' she captioned the image. 'Some days he pokes out more than others but he's in there lol [sic].'

Katherine jokingly posted a picture of her stomach shortly after eating a McDonald's three months prior to announcing her pregnancy.

In the funny social media snap, the model shared an image of her bloated post-fast food stomach, before sharing another shot of it looking trimmed, toned and back to normal just a few minutes later.

'Guess what??? I am so excited to announce that I am 20 minutes preggers with an Egg McMuffin,' she wrote, before adding: 'Thank you McDonalds breakfast all-day for this wonderful blessing. I can poke out this food baby so good #reallytho.'

While most of her followers assumed it was just a joke at the time, it turns out that the onetime Sports Illustrated model was actually two-months pregnant when posting the snap.

Katherine gained fame during her appearance at the 2013 BCS National Championship Game, when college football announcers began paying more attention to her beauty than what her then-boyfriend AJ was doing on the field.

AJ, meanwhile, was the star quarterback at the University of Alabama, and was a runner-up for the Heisman Trophy in 2013.

He was drafted by the Bengals in the fifth round of the 2014 NFL draft. A few months later, AJ and Katherine tied the knot in a lavish ceremony by the Gulf shores in Orange Beach, Alabama.
