Pregnant Brittany Matthews Puts Baby Bump on Display While Modeling a Trio of Outfits
The trainer is expecting a daughter with fiancé Patrick Mahomes
Brittany Matthews is bumping along!
The pregnant fitness trainer, 25, modeled three outfits on her Instagram Wednesday, sharing a trio of mirror selfies that showcased her baby bump while rocking pieces from Balance Athletica. "Outfit 1, 2 or 3????🤩," asks Matthews, who is currently expecting her first child, a girl, with fiancé Patrick Mahomes.
Matthews smiles in the at-home snapshots, modeling the ensembles while one of her dogs — who was part of their super-sweet sex reveal celebration — rests in the background. A commenter even showed love for a "cute" hat she wears in the first pic. "thanks my cool nanny got it for me," she responds.
Last month, the mom-to-be shared what she has learned while carrying her daughter. Matthews has previously kept her Instagram followers updated about continuing to work out while pregnant, so she offered tips and advice she's picked up along the way.
"One of the most important things I have taken from pregnancy is, GIVE YOURSELF SOME GRACE!!!" she wrote, sharing a series of videos in which she demonstrates leg and shoulder routines. "Understand your body is changing, you're growing a whole human inside of you, so do not be so hard on yourself!"

"The amount of times I workout in a week fluctuates every week, and sometimes I don't get a workout in at all, and that's okay!" she said. Matthews added that her top three "priorities" are to "just move, drink your water [and] eat appropriate amount of cals."
Matthews announced that she is expecting back on Sept. 29 with an Instagram post featuring two photos with her fiancé, in which she held up a sonogram as Mahomes hugged her belly. "Mom & Dad, taking a small detour to the wedding❤️," she wrote at the time. The athlete shared a close-up photo of the sonogram to his own Instagram feed, captioning the post with a red heart emoji.
The longtime couple — who began dating in their teens — got engaged earlier that month, when Mahomes popped the question following the Chiefs' Super Bowl ring ceremony and one day after Matthews' birthday.
